Arab Post Day update and more to come

by Richard Zimmermann

Both previous blog pages triggered attention from collectors and resulted in additional information that help complete the catalogue:

Regarding the Arab Postal Day issue [T20250803], two additional countries have to be added to the already reported list (Algeria, Iraq, Tunisia, and the United Arab Emirates) namely, Egypt and Oman which issued their stamps respectively on August 3, 2025 and August 10, 2025 (Information provided by Mohamed Achour Ali Ahmed, Algeria and Ali Allawati, Oman).

The 80th Arab League anniversary issue from March 22, 2025 [T20250322] was also completed by two stamps issued in miniature sheets of 3 pairs from the United Arab Emirates. These stamps were issued on August 18, 2025 (Information provided by Kenneth Sequeira, Singapore).

The previous blog page was also missing the image of the Russian stamp jointly issued with North Korea on August 15, 2025. Illustration was provided by Kenneth Sequeira, Singapore, confirming the twin character.

I also made a comment earlier that embroided stamps are never used postally. Henri Aronis (France) provided a proof that this can happen with a Swiss stamp (year 2000), although not part of a joint issue. As expected, the thickness of the ‘stamp’ makes cancellation illegible. This cover was sent from Switzerland to Niger. Thanks Henri.

Jaap Sarelse (the Netherlands) reacted on the comments provided earlier about the July 5, 2025 Cape Verde – Portugal joint issue and at the same time provided information about Angola, a third country joining this issue, with the following:

“The text suggests that it is a joint issue in which only Cape Verde and Portugal are involved. However, Angola is also involved with an identical stamp. Not to commemorate Angolan independence, but purely focused on the independence of Cape Verde. Some evidence:

  • In the leaflet of the Portuguese Post (6 pages) the text on page 5, 7th and 8th line from the bottom reads: ‘To help consolidate the historic memory of the founding of the Republic of Cabo Verde, a joint stamp issue is being released by Angola, Cabo Verde and Portugal’.
  • On page 5, one can find the stamps of Angola on the top row. Cabo Verde is also mentioned on this stamp at the bottom right.
  • Finally, only Cabo Verde is mentioned in the logo on page 1. I suspect that in the context of ’50 anos Independência Nacional’ Angola will get its own joint issue and that the name Angola will then adorn below the stars in the logo“

Thanks, Jaap for this complement. Catalogue will be updated. Here are the additional illustrations (Angola stamp illustrations provided by Kenneth Sequeira):

Additional information relative to issues to come include the following:

  • The Oman – Russia originally scheduled for April 22, 2025, is now postponed to September 26, 2025 (Oman source) or October 15, 2025 (Russian source), not clear at this stage. It will show maps and honour Omani explorer Ahmed bin Majid and the Russian traveler Afanasy Nikitin
  • Kenneth Sequeira reported also two modifications in the Russian philatelic programme for 2025: a) the RCC stamps will be issued on August 23, 2025, but over the past years these stamps involving all CIS countries were not anymore considered as joint and there is no hint that this will change this year; b) the anniversary of the liberation of Korea will be celebrated by overprinting the August 15, 2025 joint issue with North Korea. These stamps will be issued on September 2, 2025
  • On October 7, 2025, the France – Japan is also confirmed. Japan stamp designs became available (information provided by Dominique Josse, France)

  • On August 15, 2025, Argentina issued a stamp to celebrate 60 years of immigration from Korea. No stamps related to the same topic was seen so far in the South Korea philatelic program. This issue may remain unilateral (information provided by Enzo Cafaro, Italy)

  • Our friend Luis Alejandro Malanco Reyes (Mexico) is working on a Mexican stamp catalogue (which of course includes also joint issues involving Mexico) and brought on line the first part of his work (years 2001-2025) with free access: Catálogo Filatélico México . Congratulations Luis and keep doing the good job.

Finally, some information about the next joint crypto-stamps issue (not recommanded to include in the joint issue collection as explained earlier): This will be the fourth crypto joint issue after the 2022 Austria-Netherlands (Ox), 2023 Austria-Luxembourg-Netherlands (Lion) and 2024 Austria-Belgium-Luxembourg-Netherlands (dragon) issues. The theme for this fourth issue is the Greek world of the gods. Five countries will participate and they made the following choice: Portugal – Poseidon, Austria – Zeus and Hera (2 stamps), Belgium – Athena, Luxembourg – Artemis and the Netherlands – Hermes.

Jaap Sarelse has succesfully created joint stamp covers with the previous crypto stamps and will try again this year with the six stamps. He provided the picture of the copy from year 2024. Such documents are close to unique.

The catalogue was update with all above new data. See updated Vol 1, Vol 15 and Vol 16

August 2025 News

by Richard Zimmermann

Enzo Cafaro (Italy) completed the information about the dove issue described in a previous post and enhanced the list of participating countries. He provided also the picture of all to be produced items. The country list includes now : Aland, Armenia, Austria, Cyprus, Faroe Islands, Greenland, Liechtenstein, Luxembourg, Switzerland and United Nations (offices of Geneva, New York and Vienna, as well as UPU). By adding all the denominations we reach a total of about 75 Euros for 13 stamps that will never be used on real covers ! Our friend Jaap Sarelse (the Netherlands) will try to create some mixed FDC covers when stamps will be available. We wish him good luck as even the cancellation on such thick stamps (embroidery) may be tricky. If he succeeds, we promise to show results in these pages 😉

Luis Malanco (Mexico) provided some additional information regarding the Ecuador stamps issued on July 28, 2022, together with Mexico [T20220728] and honoring Leona Vicario and Manuela Saenz. The Ecuadorian stamps were issued at a much lower number than initially announced. The stamp was produced at only 2,000 samples, while the souvenir sheet only at 450 units. Those are the figures appearing in the official leaflet published by the “Servicios Postales del Ecuador”.

By coincidence, a forgotten issue was discovered recently by comparing data in the Michel Rundschau Catalogue. On December 29, 2022, Cambodia and Colombia issued twin stamps at the occasion of the 50th anniversary of diplomatic relationship between both countries. The stamps show a view of Ankor Wat and the Grave in the Archeological National Park of Tierradentro. This issue has not been reported so far and will of course be integrated in the catalogue. The difficulty will now be to find the stamps and not only reproductions.

During the year 2021, Colombia celebrated the 200th anniversary of its independence. Numerous stamps related to this event were issued during this year, which correspoded also to the first recognition of Colombia by other countries. By end of 2022, a first joint issue with Mexico was released (December 20, 2021). Surprisingly, during the following year of 2022, Colombia created a series of different stamps celebrating diplomatic relationships with different countries (not necessarily based on 200 years, but at least on rounded numbers): Egypt (February 23, 2022), USA (May 2), South Korea (May 6), Peru (May 27), Germany (August 5), Cambodia (December 29) and Chile (December 29. This type of issues continued the following year with Barbados (December 18, 2023), Canada December 22) and Argentina (December 23). During the year 2024, only stamps celebrating relationships with Sweden were released (exact issue date is unknown). Among all these stamps, and to our knowledge, only four translated in true joint issues, including Mexico [20211220], Peru (T20220527], Cambodia [C20221229], and Argentina [T20231223]

The design of the North Korean stamps to be released jointly with Russia on August 15, 2025 has been released. We have not seen yet the Russian stamps, but this country confirmed stamp issue in this honour at the same date. Design could be similar.

Last minute information: Kenneth Sequeira just provided information about stamps released by the Philippines on August 5, 2025, jointly with India, celebrating the 75th anniversary of their relationship. Each country issued a pair of identical stamps showing flowers. Note that despite being issued in 2025, the stamps celebrate an anniversary that took place in 2024.

Catalogue 2025 updated

by Richard Zimmermann

The new catalogue of Joint Stamp Issues 2025 is now on line with the section of the stamps issued during the year 2024 fully updated. In order to keep an average of about 100-130 pages per volume facilitating a quick downloading, the year 2024 needed to be separared from the 2022-2023 period (Volume XV) and a new volume numbered XVI, containing years 2024-2025 was created.

This new updated catalogue, the 2025 version in 16 volumes, has now reached 1,900 pages. It contains over 2,280 entries among which more than 1,580 can be considered as true joint issues (unique, se-tenant, twin, concerted or parallel). It describes in total more than 16,100 items, and it is illustrated with above 8,900 pictures, providing also more than 35,100 quotations. This upgrade allowed also to make a comparison of the evolution of the number of issues of joint stamps for statistical purpose, which leads to a graph looking as follow:

It appears that after a strong progression over the years 1980-2010, the number of new yearly issues reached a kind of plateau over the past 15 years, with an average of 40 issues per year. The progression affected only the twin joint issues while the number of parallel/concerted issues remained stable over the past 50 years. However, the number of different products for each issue such as additional souvenir sheets, booklets, miniature sheets or mixed cancelled products, or the number of total stamps per issue did progress as well. In parallel, we have also to observe that the number of abusive joint issues (issues involving a high number of countries not fully controlled by the local postal administrations, but printed centrally) has increased. We will still continue to identify those issues separately, and even if we continue to have them described in the catalogue for the sake of completeness (gray color and italics characters), it will remain up to the individual collectors to decide if they want to include and purchase them. Typically, these stamps will not gain value over time, will be difficult to resell and are usually not accepted in exhibitions.

Joint issues are a mirror of the political state of the world. The increasing number of conflict situations is not in favor of a progression of the number of joint issues. Several planned issues were cancelled during the past five years, due to political concerns. My wish for the next year(s) is to be able to report soon a first joint issue e.g., involving Israel and Iran, North and South Korea or Ukraine and Russia, which would become the best sign of a progression toward world peace.

Among the major improvements, note that at least 25 new items describing mixed FDCs have been added over the period 2021-2024. We own a huge thank to Jaap Sarelse (The Netherlands) for his great work and time spent over the past 30 years in providing this information, finding the items and even trying to create such mixed products whenever possible. The existence of mixed first day cancelled products remains the ultimate proof of the joint character as both postal administrations must have agreed for the production and existence of such items.

On top of the additions of new 2024 issues described in previous blog pages, one has to note the following:

On September 14, 2024, Bangladesh re-issued an older stamp from 2001 with a handstamp “DHAKAPEX”. This issue is now described in the catalogue under the original stamp heading [T20011009] together with all the other stamps of the same series. This gave the opportunity also to update the texts and images of these stamps in the catalogue as this entry was only partially illustrated. As much as 75 new images over three pages were introduced to illustrate this entry.

The International Telecommunication Union (ITU) is celebrating during the year 2025, its 160th anniversary. The UPU did send on October 28, 2024 a circular to all its members, asking that if they want to commemorate this anniversary, they can use the new logo of the event. The way this letter is presented clearly shows that this is not a call for a joint issue. So, at this stage and in absence of further notice, stamps that will be produced during the year 2025 and bearing the below logo will not be considered as joint, as they are simply commemorative stamps based on individual initiatives.

On the contrary, the design of the 2026 PostEurop stamps to be issued at the occasion of the 70th anniversary of PostEurop, was released by beginning of January 2025. A common stamp will be used at this occasion, based on a contest that a Finnish group did win.

One has also to note a small modification regarding the December 20, 2021 issue involving Colombia and Mexico. The Mexican stamps were issued on December 20, 2021, but the Colombian stamp became only available on January 25, 2022. However, it appears that the Colombian FDC and the mixed FDC are still cancelled from December 20, 2021. This issue which was initailly considered as a Concerted one under the heading number C20211220 is now reported as the twin issue T20211220.

The same modification affected the stamps issued on October 16, 2023, involving Vietnam and India. Small amounts of Vietnam stamps became available at one post office at the original day of issue (April 28, 2023), but stamps were retrieved after sale of the first batch of 4,000 units. India announced three times the release of their stamps until they became eventually available on October 16, 2023. These delays led to consider initially this series as Concerted. However, the mixed FDC of this issue is cancelled with dates from October 16, 2023 for both countries and therefore these stamps are filed as twin [T20231016]. Covers with Vietnamese stamps cancelled before October 16, 2023 are rarities.

UPU 150th anniversary

by Richard Zimmermann

The Universal Postal Union (UPU) is a specialized agency of the United Nations (UN) that coordinates postal policies among member nations and facilitates a uniform worldwide postal system. It comprises 192 member states and is headquartered in Bern, Switzerland. It was established on October 9, 1874, exactly 150 years ago.

Since more than one year, we know that this anniversary will be celebrated with a stamp which common design was proposed by UPU. In the past, the 75th (1949) UPU anniversary was celebrated, but in a non-coordinated way, mainly by colonial entities (British, Dutch and French – D19490704, D19491001, D19491010, D19491018) and the 100th (1974) anniversary with stamps that remained different for all participating countries (N19741009). The same situation happened in 1999, with absence of concertation for the 125th anniversary celebration (N19991009). Eventually, so far, only the 145th anniversary in 2019 (T20191009b) could be considered as a Twin issue.

During this year of 2024, a very large number of countries are participating. In the strict sense, this has to be considered as a true joint issue, even if there was no real cooperation between countries, but a proposal of a design accepted by most of them and translated in a locally adapted stamp, for a large part of them issued at the anniversary date. It is not an Omnibus series, as Omnibus is defined by a central printing, not by the large number of participating countries. The 2024 stamps will be reported in the catalogue as a Twin issue under [T20241009]. It is easily understandable that some joint issues collectors do not integrate such large series in their collection, in the same way Europa-CEPT stamps are not acceptable for them. Each individual collector has to decide on the basis of the following.

In the catalogue, the countries will be divided in subgroups:

  • A: the countries which take the exact original design proposed by UPU and issue the stamp(s) on October 9, 2024 (or actually around this date, plus or minus a week, roughly between October 1 and October 17, 2024), according to the definition of a twin issue [T]
  • B: the countries which take the exact original design but issue the stamp at a different date. It should not be surprising if some countries may issue their stamp in 2025 or even 2026. This is the equivalent of a Concerted issue [C]
  • C: the countries which use only a part of the design, actually integrating only the “150” logo and add some other illustrations. This logo can appear within the stamp, or on the margin of a souvenir sheet or within a label. Those stamps are also considered as twin or concerted issues of Type [T2] or [C2]
  • D: the countries which use a completely different design, but still issue their stamp(s) around October 9, 2024. This is the equivalent of a Parallel issue [P]. In this case, the original logo may appear on the stamp, but at a size that remains smaller than the half of the surface of the stamp
  • E: finally the countries that do not want to stick to design and date, and work on their own, just referring to the UPU anniversary. These countries are simply listed, without details, as they cannot be considered as joint [N].

We will have again to take care of stamps that are created by agencies that are producing stamps for certain countries but which have been given the freedom to issue stamps without a real control from the reference countries. These stamps are easily recognized by the number of stamps issued in a series and they are produced to fool collectors. In order to better identify these stamps and because they remain real stamps but never reach the originating country, they will be reported in the catalogue, but in italics. In the same way, some other stamps such as the French stamp with a full common logo are of private origin (personalized stamp) that cannot be considered as part of this joint issue either. This will be true for any other privately produced stamp from other countries, if any, and also described in italic characters.

The countries for which we already have information are reported below. If a date between brackets is missing behind the country name, this means that this stamp(s) was issued on October 9, 2024. If the content of the brackets remains empty, this means that the exact issue date is not known yet. A large number of images were provided by Enzo Cafaro (Italy). The following list is of course not yet complete.

Countries of type A (Twin [T1]): Algeria – Andorra (French) (October 10) – Andorra (Spanish) – Armenia – Bangladesh – Belarus – Bosnia Herzegovina (Bosnia) – Brazil – China (PR) – Croatia – Cyprus – Dominican Republic – Greece – Guernsey – India – Indonesia – Ivory Coast – Jordan – Latvia – Lithuania (October 4) – Mauritius – Moldova – Myanmar – Paraguay – Peru – Romania – Sri Lanka – Thailand – Turkmenistan (October 8) – Ukraine – United Arab Emirates

Countries of type B (Concerted [C1]): Argentina (August 28) – Azerbaijan (February 1) – Burundi (September) – Central Africa (September) – Djibouti (September) – Georgia (June 1) – Guinea (September) – Guinea-Bissau (September) – Liberia (September) – Mali (September) – Monaco (May 30) – Mongolia (September 25) – Sierra Leone (September) – Togo (September)

Countries of type C (Twin or concerted [T2] or [C2]): Bosnia (Serbia) – Egypt () – France (October 14) – Hong Kong – Hungary (July 24) – Isle of Man (August 30) – Japan – Kyrgyzstan (October) – Luxembourg (September 10) – Macau – Malaysia – Morocco – Pakistan – Portugal – San Marino – Saudi Arabia () – Singapore – Slovenia – Spain – Syria – Tunisia – Türkiye – Uruguay – Uzbekistan () – Vietnam

Countries of type D (Parallel issue [P]): Australia (October 1) – Austria (October 4) – Brunei Darussalam () – Bulgaria – Czech Republic – French Polynesia – Germany (October 10) – Macedonia (North) – Mexico – Montenegro – Qatar () – Russia – Slovakia – Switzerland (September 5) – Tajikistan (May) – Vatican (September 16) – Wallis and Futuna

Countries of type E (not considered as joint): Belgium (June 10) – Serbia (May 25) – United Nations – Geneva (May 30) – United Nations – New York (May 30) – United Nations – Vienna (May 30).

So far, 86 countries are listed above to which one has to add 2 postal authorities that have issued stamps that cannot be considered as joint (Type E – United Nations offices are not taken in account as countries, UPU being a sub-unit of the United Nations). The UPU counts presently 192 members, which means information from 106 countries (!) is missing. Obviously there will be an update of this page. A great help is needed here to recover information from other participating countries. We are also missing better quality images for stamps from Ivory Coast and Ukraine. Thanks a lot in advance for providing name of missing countries, exact dates of issue, and when possible illustrations, printing runs, sizes of panels and by-product lists.

The catalogue pages should be updated within the next week.

Liechtenstein – Mexico (additional)

by Richard Zimmermann

Following the publication from the previous blog page about the July 3, 2024 announced as unexpected Liechtenstein-Mexico joint issue, some doubts raised about the real status of this issue. Both countries issued a pair of identical se-tenant stamps showing mountains from both countries : Alpspitz (Liechtenstein, 1943m) and Mineral del Chico, Hidalgo (Mexico, 3200m). 

Comments came from Luis Malanco (Mexico), Lars Kersten, Jaap Sarelse (The Netherlands), Enzo Cafaro (Italy), and Philatelie Liechtenstein. Thanks to all of them.

While Mexican Post provided all details about the Mexican stamps (sheets of 25 pairs, printing 50,000 pairs, FDC available), the Liechtenstein stamps were never disclosed on the Philatelie Liechtenstein web site. These stamps are not listed in the official Liechtenstein philatelic programme, are not for sale through the web page and are not described in the June or September Liechtenstein official brochures. Official events in Liechtenstein and Mexico took place to celebrate the anniversary of this diplomatic relationship, in the presence of representatives of both postal entities (see below some illustrations of web media pages provided by Luis). All stamps were disclosed during these events.

(VIPs mentionned in these blogs: Luis Seger is Executive Director of Liechtensteinische Post; Pietro Piffaretti is the Ambassador of Switzerland in Mexico; Rocio Barcenas is a Director of Correos de Mexico; Cecilia Jaber is the Ambassador of Switzerland and Liechtenstein in Mexico; Dominique Hasler is the Minister for Foreign Affairs, Education and Sport with the Government of the Principality of Liechtenstein). Here are also two links with events organized in Liechtenstein (Link 2). All these events took place on July 2, 2024.

Lars pointed to the fact that the Liechtenstein stamps bear the name “Liechtenstein” instead of “Fürstentum Liechtenstein”. The country name alone applies apparently to personalized stamp, which are not available through the official channels. The day following the issue, the stamp was considered by Liechtenstein Post as sold out. Answers from Philatelie Liechtenstein (via Jaap): “The stamps of 30 years of diplomatic relations between Mexico & Liechtenstein have been issued as a small edition in digital printing and are unfortunately already sold out.” Later additional information came from the same source under the form: “1. The Mexico-Liechtenstein joint issue was a personal stamp under the authority of Liechtenstein Post. 2. The issue number was very low, and we are unable to provide any further information on that question. 3. There is no FDC as FDCs are only produced for official issues.“. We still are waiting for information about who gave the order for printing and who acquired all the stocks.

In conclusion, these Liechtenstein stamps must be considered as a private issue. These stamps will be described in the catalogue, but under the entry code [N20240704], ‘N’ standing for ‘Non-approved’, based on the criteria defining a true joint issue in Catalogue Vol 1. However, these Liechtenstein stamps do exist (even if in a very limited edition), can officially be used for postage and therefore have to be considered as true stamps. It is up to each collector to decide if he wants to integrate ‘N’ stamps in his own collection. We have not seen these stamps so far and do not know from where to buy them. Additional information remains welcome.

Unexpected Liechtenstein – Mexico 2024

by Richard Zimmermann

Luis Malanco (Mexico) provided images of an unexpected Liechtenstein – Mexico joint issue at the occasion of the 30th anniversary of their relationship. The stamps were released on July 3, 2024. Both countries issued a pair of identical se-tenant stamps showing mountains from both countries : Alpspitz (Liechtenstein, 1943m) and Mineral del Chico, Hidalgo (Mexico, 3200m). Unfortunately, beside the pictures, very limited information is available so far.

September 2023 News

by Richard Zimmermann

The month of September led to more new products than the whole preceeding Summer period including some surprising items, next to the already reported PAPU issue (7 countries), the China-Hong Kong – Macau series and the Switzerland – South Korea stamps.

Don Birschel, USA, reported about an unexpected joint issue between Guatemala and Mexico, released on September 18, 2023 and related to the 175th anniversary of their relationship. The stamps represent the Pyramid of the Sun, San Juan Teotihuacan, Mexico and the Tempel of the Great Jaguar, Tikal, Guatemala (pre-Columbian Maya civilization). Don provided the images, but we are still missing some details about the Guatemala stamps.

The 200th anniversary of the relationship between Argentina and Brazil translated into a stamp showing the Iguazu falls at the Brazilian-Argentinian border, issued on September 7, 2023, while Brazil released on September 29, 2023, a panel of 8 stamps showing Mafalda comics from the Argentinian artist Quino. Despite the common title, this issue cannot be considered as joint (different dates of issue, different designs, no claim as joint – information provided by Enzo Cafaro, Italy).

On September 26, 2023, San Marino issued a stamp related to the 15th anniversary of relationship with Mexico. No Mexican counterpart was seen so far, and probably nothing has to be expected from the mexican side.

More recently, on October 2, 2023, Slovakia issued, jointly with Azerbaijan, stamps at the occasion of their 30 years of relationship, the same day Slovakia issued stamps with the Czech Republic (see previous blog page). This series describes folk music styles illustrated with string instruments: the Terchova region music and the Mugham Azerbaijani folk music. Azerbaijan has issued the stamps apparently only as a souvenir sheet at only 5,000 samples (Information provided by Eric Contesse, France).

A new crypto stamp (NFT) joint issue, to be released during the month of October 2023 (probably on the 23rd), was announced involving Austria, Luxembourg and the Netherlands. Stamps are similar. More details soon. For explanations about crypto stamps, see austria-netherlands-crypto-stamp.

There is still a problem with these new products: crypto stamps are always very expensive, their value is linked to crypto money that is fluctuating a lot over time (value of previous NFT stamps has dropped a lot recently) and above all, these so-called stamps are never used on real mail. To our opinion, they are more to be considered either as a piece of art or as a kind of currency, and seem to stay away from real philately (in terms of collecting items used to compensate for mail fees). Eventually, look like material to fool the collectors (abusive issues). Those stamps have to be reported in the catalogue as they are claimed as joint issue “stamps”, but there is no recommendation to buy them. On the other hand, a collection of such stamps on cancelled mail, i.e., for real non-philatelic mailing purpose, would be a real interesting topic. Apparently, in none of these countries, the denomination corresponds to a true postage fee and their use alone on a cover should not exist (except on FDC covers).

Update: January 2023

by Richard Zimmermann

Without specific priority, the following descriptions collects information provided by friends since beginning of the year. Many thanks to Enzo Cafaro – Italy, Don Birchel – USA, Wayne Chen – USA, Jaap Sarelse – the Netherlands, Roland Montagne – France, David Dubin – USA, Souvik Ghatak – India, Milan Csaplar – Slovakia and Kenneth Sequeira – Singapore.

In the continuation of the production of Arab countries stamps celebrating the 2022 FIFA soccer worldcup, next to Jordan and Oman (stamps issued on December 18, 2022), we learned that the exact date of issue of the Qatar souvenir sheet was January 17, 2023. Obviously this series is not yet complete.

During the official visit of President of Egypt, Mr. Abdel Fattah El-Sisi to India, a joint stamp on the “75th Anniversary of Diplomatic Relations” (1948-2023) was released in form of a souvenir sheet which theme is rivers, The Ganges (India) and The Nile (Egypt) are represented on the stamps. Release date was January 25, 2023. However, so far, there are no information from the Egyptian side about a similar product. Actually, Egypt had issued on August 18, 2022 and unilateraly, a stamp celebrating this anniversary. Unfortunately, there are great chances that this Indian souvenir sheet remains unilateral as well and just corresponds to the counterpart of the 2022 Egyptian stamp. Therefore, these two items cannot be considered as joint (yet).

Poland issued on January 29, 2023 a stamp dedicated to the 550th birthday of Nicolaus Copernicus. This celebration is still reported in the Vatican philatelic program as joint stamp with Poland, but Vatican State has not released anything so far. So, we need to wait for news from this state before adding this issue in the catalogue. Due to the difference in time for issuing their stamps, this pair can now only become a concerted issue, providing also the design remains the same. If the design is different, then it does not even have a joint character.

Wayne Chen (USA) could announce the publication of his newest article on Crypto stamps, published in Linn’s Stamp News on line on February 4, 2023 (printed form publication date February 20, 2023), which also made the cover story for the monthly version of the magazine. At the end of the article, a list of the stamps mentioned in the article that were issued 2018-2022 is provided for those interested in this new (and expensive) collection. regarding our interests, the mixed cover of the first joint crypto issue (Austria – Netherlands [T20220922] is reproduced. It was provided by Jaap Sarelse (the Netherlands).

A new item from Ecuador associated to the 2022 Ecuador – Mexico joint issue [T20220728] appeared as well, late after the official issue date. A souvenir sheet, vertical form size 65x185mm, without gum and stamp with same denomination ($0.75), numbered at the bottom, but priced $5.00 was released by Ecuador. Exact printing run is unknown, but it seems that 5,000 stamps and 3,500 souvenir sheets became available. This item has been added in the catalogue. Also, it is told that the first day cancellation of the stamp exists only at 30 samples. Ecuador post offices are still under reorganization.

The designs of the 100th anniversary of custom treaty stamps involving Liechtenstein and Switzerland were released. These stamps will be sold from March 29, 2023 on.

In terms of new issues to be added in the list of stamps expected to be released during the years 2023 and 2024, we can mention the following:

  • During the year 2023, Morocco plans an exceptionnally large number of joint issues with Oman (May), Romania (August), UAE (November), Kazakhstan (December) on top of its participation to the Euromed series (July)
  • The Cyprus – Israel joint issue will be released on April 4, 2023 and not in February as earlier mentionned
  • Austria – Germany – Slovakia : May 24, 2024 – Limes Romanus of the Upper Danube

2022 JI collecting year: a review

by Richard Zimmermann

A year has been completed again. There is now little chance that a last minute 2022 joint issue is discovered and therefore the chapter 2022 in the catalogue can be closed as well. Information, images, and quotation have been updated for this full year.

Unfortunately, there are still missing information from some countries from which joint partners were expected. The Iran-Kenya stamps showing coffee beans and safran flower stamps and dedicated to the 50th anniversary of the establishment of Iran-Kenya diplomatic relations remain as a unilateral souvenir sheet issue from Iran on June 24, 2022. No information about Kenyan stamps issued during the year 2022 has been published. The situation is identical for the Iran – Serbia souvenir sheet (85 years of diplomatic relations, September 30, 2022) for which information about the Iranian stamps is missing. These unilateral issues have been removed from the catalogue, but in the case someone finds the missing information, here are the pictures of the issued stamps as a reminder.

The India-Vietnam and India – Thailand joint issues respectively announced by Vietnam and Thailand in their 2022 philatelic programs did not come to a finalized product. These joint issues may be rescheduled in 2023 but had to be removed from the catalogue as well.

Altogether, this allowed a complete update of the catalogue becoming now the 2023 edition V4.0 and all the 15 parts have been modified (mainly shift of pages) with minor improvement in each of the part.

At the same time, this work gave us the opportunity to provide some statistics about the joint issue season 2022. In terms of figures, the year 2022 translates in the following: there are 51 entries reported in the catalogue for the year 2022, but among which only 40 are true joint issues: 1 Se-tenant [S] but no Unique [U], 27 Twin (same design, same date of issue) [T], 7 Concerted (same design, different date of issue) and 5 Parallel [P] (same date of issue, different designs) issues. Additionally, we reported 2 Omnibus series [O], 2 Territorial issues [D] and 1 issue with Borrowed design [B]. For the year 2022, the catalogue provides 225 illustrations, describes 344 items together with 675 quotations.

Another interesting point relates to involved countries. As many as 66 countries participated at least to one true joint issue, but the winner is surprisingly Mexico with 7 participations. Mexico is followed by Russia (5 times, almost exclusively with Asian eastern countries) and by the group Argentina, Egypt, Georgia, Oman and Vatican which were involved 4 times each. This high participation of Oman and Georgia are also quite a surprise. Eventually Armenia, Belarus, Israel, Poland, Tunisia and the UAE were involved 3 times each. There are no new first comer in this 2022 list, but it is interesting to notice the come back of countries such as Cambodia, North Korea or Tanzania. This year also saw the issue of the first joint crypto stamps between Austria and the Netherlands.

The new version of the catalogue in 15 volumes describes over 1,750 pages, 2,150 stamp issues among which more than 1,500 are true joint issues, and provides more than 8,100 illustrations. 32,900+ quotations are linked to more than 14,800 different items.

Note also that from now on, and in order to reduce the amount of intermediate versions in the archive files, only the first edition of each year will be kept accessible. Numbering of intermediate version will continue to be used, but at the beginning of each year the versions with small modifications will be erased. The first version of each year will play the role of reference for earlier catalogue versions. Edition 2023 intiates the publication of V4.0.

To complete this exercice, it becomes also interesting to show the evolution of the production of Joint issues over the past years. On the basis of the catalogue entries, it became possible to create the following graph which shows the number of joint issues released each year since 1960. The blue curve gives the evolution of the number of Twin issues [T], the orange curve the combined Parallel [P] and Concerted [C] issues and the grey curve the total [T]+[P]+[C] including also the rare Unique [U] and Se-tenant [S] issues. Omnibus [O], Territorial [D] and Borrowed design [B] issues are not included in this graph. The peak release was reached in 2019, just before the Corona pandemic, with 53 true joint issues in one year, but the graph shows also an apparent plateau of around 40 issues per year that stays since 2007. Over this 15 years period, the number of products for a single country, and in particular by-products such as souvenir sheets, miniature sheets and even stationery, did continue to increase (not shown on the graph). A peak production of items above 500 was reached during the years 2016 and 2019, while the average figures since 2007 over this period was maintained around 280 (with severe variations during the Covid period, 230 in 2020, 140 in 2019 and back to 340 in 2022).

At this time it is difficult to predict the progression for the next years, but a stabilization around 40-45 issues per year would make sense. Continue enjoying collecting joint issues and have a nice year 2023.

Latest news – December 2022

by Richard Zimmermann

A series of new information has come to our attention over the recent weeks thanks to Enzo Cafaro (Italy), Don Birschel (USA), Kenneth Sequeira (Singapore), Grzegorz Smialkowski (Poland) and Ali Ahmed Med Achour (Algeria).

The picture of the Argentinian stamps issued jointly with Poland became available. These stamps were issued on November 25, 2022, the same day as the Polish stamps, but it took all this time to get the information. Poland issued stamps in miniature sheets of 4 pairs of se-tenant stamps, while Argentina issued panels of 4 strips of two se-tenant pairs separated by a label showing the logo of the 100th anniversary of the diplomatic relations between both countries.

In a same way, Enzo Cafaro could eventually provide the information about the identical stamp produced by Mexico jointly with the Vatican State. Vatican stamps were released on November 16, 2022 (sheetlets of 10 stamps), but one had to wait until December 12, 2022 to see the Mexican stamp (sheets of 50).

Georgia and Poland have issued joint stamps to honor Georgian Theologian Grigol Peradze (1899-1942) who died in 1942 at the Auschwitz concentration camp. The stamps were released on December 6, 2022, for both countries in miniature sheets of 8 stamps.

Georgia is also involved in a joint issue with Azerbaijan issued on December 7, 2022. This issue is celebrating the 30 years of diplomatic relations between both countries, also in miniature sheets of 8 stamps each.

We found also two new countries to add to the World Postal day series from October 9, 2022, on one side Indonesia (detailed information still missing) and on the other Saudi Arabia which issued 5,000 stamps in miniature sheets of 6. We have now reached 24 participating countries, and the list does not seem complete yet. Presently, it includes: [2022 (October 9)]: Argentina – Belarus – Bosnia Herzegovina – Cambodia – Central African Republic – Colombia () – Croatia – Djibouti – Egypt – Fiji (September 22) – Guinea Bissau – Iraq () – Mexico – Russia (October 7) – Saudi Arabia – Serbia (October 7) – Sierra Leone () – Sri Lanka – Syria – Thailand – Tunisia – Turkey and Venezuela (). Empty brackets need to be filled with the precise dates of issue.

It seems that the Arab Postal Union has agreed to issue a common stamp celebrating the Soccer World Champion Cup in Qatar, based on a Qatari design, but even if this event is reaching its end (December 18, 2022), very little is known about it at this stage. Hopefully moreto say next time.

Among the new series to be released during year 2023 we have to add Cambodia – Korea (South) (February 10), China – Spain (March), India – Korea (South) (July 28), Korea (South) – Switzerland (September 7) and Hungary – Thailand (October 24). Of course, more to come as well.

Finally, I would like also to mention a new address of a blog I came accross while evaluating the new joint Crypto/NFT stamps, namely Bitter Grounds Magazine, written by Catpaw, which gives news about stamps from the year but also some stamp programs for 2023, and provides a weekly newsletter. An interesting source of information. Congratulations to Catpaw.

Monthly news (November 2022)

by Richard Zimmermann

Additional information related to the World Postal Day issue from October 9, 2022, [B20221009]: two new countries have to be added. First Iraq issued a stamp at a date that still needs to be confirmed, but probably also October 9, 2022. The second one, Venezuela, issued a stamp in miniature sheets of 6 (date of issue and high quality picture are missing). There are high chances that the list of presently 22 countries is still not complete. Additional information is welcome.

Note also that the Mexican stamp has been issued in panes of 50 stamps, but the miniature sheet of 6 stamps that was issued in parallel in fact contains 6 different stamps with heading in 6 different languages. The stamp in the middle of the first row (Spanish language) is the one issued in panes. As in items seen so far a printing number is added at the bottom right of each sheet, it seems that less than 1,000 miniature sheets have been printed.

Extension of the Austria Netherland crypto stamp from September 22, 2022. Another pair of joint crypto stamp was issued on November 22, 2022. This is the gold form of the previously issued crypto stamps, provided each with a 1g golden bar embedded in the card. The denomination is “R” for the Netherlands (999 samples), but “500,00” for the Austrian stamp (499 samples) sold at € 500. It is without saying that except if you are a collector of crypto stamps, we absolutely do not recommend to buy this item as part of the joint issues collection. With this low edition number, it is simply a product to fool collectors and the high price must be considered as a high risk investment. However, the product will be described in the catalogue in italic characters without providing a quotation. (as a reminder, the real value of a 1g bar of gold is estimated today at around €54)

There are still a few joint issues to be released before end of the year. We learned (Enzo Cafaro, Italy) that the Mexico counterpart of the Vatican State stamp already released on November 16, 2022 should become available on December 12, 2022. Enzo provided also first information about a Poland – Argentina joint issue released by Poland on Novemeber 25, 2022, for which we are still missing information from the Argentinian part. The Polish se-tenant stamps represent the Rufous hornero (Furnarius rufus), national bird of Argentina and the Crestet tit (Lophophanes cristatus).

The Catalogue Volume XV has been updated accordingly and the information has been dispatched as usually in Volume I.

Argentina – Chile – Mexico

by Richard Zimmermann

Enzo Cafaro (Italy) provided the images of two stamps issued on October 22, 2022 by Mexico, entitled “Characters of history: Poetry. Portrait of characters or Christian rite”. The first one is dedicated to Gabriel Mistral (1889-1957) and bears the words “Mexico – Chile”. The other one honors Berta Singerman (1907-1998) with the text “Mexico-Argentina”. It took us more than a month before Don Birschel (USA) discovered information about the identical stamps issued by Argentina and Chile. In fact, this is a double joint issue from Mexico in which this country issued two stamps with the same style, in coordination with both other countries, while Argentina and Chile are not linked with each other. Argentina issued one stamp on October 26, 2022 in panes of 16 stamps [4×4]. Chile issued one stamp on October 25, 2022 in panes of 32 stamps [4×8], printed at 50,000 samples. The stamps of Mexico became available in panes of 28 stamps [4×7] and were both printed at 50,000 samples. Surprisingly, the cancellation of the Mexican first day cover bears the month of October 2022, but not the exact day. In the meantime, we have no other choice than to use the date of issue of the partner country. The announcement of the issue by Mexico was made on October 22, 2022.

The illustrations are 1922-1923 dated paintings from the Mexican painter Roberto Montenegro (1887-1968).
