Update February 2023

On February 28, 2023, the joint issue between Armenia and Slovakia was released as scheduled. It celebrates the 30th anniversary of relationship and the stamps depict the Tatev Monastery, in Syunik region (Armenia) built during the ninth century, included now in the UNESCO World Cultural Heritage list and the St George’s Church, in Nitrianska Blatnica (Slovakia) also from the ninth century. The particularityy of this issue comes from the way the stamps are produced. The stamps are printed in a pane size [5×9] containing both stamps, type A in the top half, type B in the bottom half, together with 5 central labels forming a central cross. The overall structure looks the following: 3 rows of 5 stamps A, a row containing 2 pairs of stamp A separated by a label, then a row with one stamp A, three labels and one stamp B, and a row containing 2 pairs of stamp B separated by a label, and at the bottom 3 rows of 5 stamps B. This structure leads to a sheet containing 20 stamps A, 20 stamps B and 5 labels. Each sheet can contain vertical pairs of se-tenant A-B stamps, but limited to two units per pane. Knowing that the total printing of stamps is 2×20,000 for Armenia and 2×100,000 for Slovakia, only respectively 1,000 and 5,000 panes have been printed containing a maximum of 2,000 and 10,000 vertical pairs respectively.

These miniature sheets could be cut a different way, by keeping in one piece the five central labels with the 2 stamps A and 2 stamps B in the four corners. Only a maximum of 1,000 units for Armenia and 5,000 for Slovakia of these cut outs of printed panels can theoretically exist. The central labels represent the flags of both countries, and the coat of arms of Armenia, respectively Slovakia. The two other labels contain the words ‘Armenia – Slovakia joint issue’ in English and Armenian for Armenia, in Slovak and Armenian for Slovakia.

Jaap Sarelse (The Netherlands) provided some information about the potential Cambodia-South Korea joint issue that was supposed to be released on February 10, 2023. The original source was the South Korean Philatelic Service. However, Jaap learned from two Cambodian sellers that no such an issue is mentioned in the 2023 list of Cambodian stamps. Also a seller from South Korea confirmed this is not a joint issue. The top margin of the souvenir sheet printed by South Korea is entitled “Protecting Endangered Species in Korea – Cambodia REDD+ Joint Project Area”, meaning the ‘joint’ character is refering to an area between both countries, and a common project, but not to this stamp issue. This entry is removed from the catalogue.

Don Birschel (USA) reports also about stamps released at the occasion of the Kuwait 62nd national day by both Kuwait (February 22, 2023) and the United Arab Emirates (February 25, 2023). Even if the Kuwait 62nd national day is celebrated by the UAE, there are no hints of collaboration between both countries and stamps are different. These cannot be considered as a joint issue.

A surprising joint issue between India and Luxembourg will be released on March 14, 2023. The information was first provided by Souvik Ghatak (India) and Kenneth Sequeira (Singapore). The Luxembourg post made the announcement as early as March 2, 2023, but it took some time for India to confirm, despite the fact that the designer of the miniature sheet is of Indian origin. The stamps relate to the 75th anniversary of the relationship between both countries and is illustrated by sculptures by Amar Nath Sehgal (1922-2007), an Indian sculptor, painter and poet who spent a large part of his life in the Grand Duchy of Luxembourg.

Up to now, there are no news from the Israel-India issue supposed to be released in the course of the month of February. In the meantime, however, the first image of the Israel stamp to be realeased on April 4, 2023 jointly with Cyprus was released. Topic is aerial firefighting. The Cyprus stamps has not been seen so far.


The following information has been added to or modified in the new version of Volume 15 (Vol 15 V4.03):

  • The above mentioned Armenia – Slovakia issue [T20230228] as well as the Poland – Slovenia [T20230306], the Poland – Vatican [T20230227] and the Ascension – British Antarctic Territories – Falkland Islands – South Georgia – Tristan da Cunha [D20230215] stamps have been integrated in the catalogue
  • Confirmation of the existence of mixed FDCs for the 2022 Argentina – Spain Juan Domingo Peron issue [C20220914]
  • Update of the list of new issues including Pakistan – Sri Lanka (2023), Japan – Peru (August 21, 2023), Japan – Vietnam (September 21, 2023)

The information related to complete descriptions of new sets of joint issues is also dispatched in Vol 1. Note that the page “Philatelic resources” is constantly updated to maintain the most accurate level (which is not easy, corrections and additions welcome) and changes will not be reported here.


Japan 2002 questionable Joint Issue

Upeka Indeewary from India did ask: “The joint issue catalogue describes a joint issue from the year 2002 involving Japan and four other countries, namely India, Bangladesh, Sri Lanka and Pakistan. It appears that in Japan this issue is not considered as joint. Can you clarify? “

Indeed this joint issue could be considered as questionable. In the catalogue Vol 8, it is already described under four different entries [P20020411 and P20020412a-c]. While Japan issued all stamps the same day, April 12, 2002, the four other countries’ stamps from India, Bangladesh, Sri Lanka and Pakistan were released with 1 to 14 days interval..

None of these countries claim a joint character, and indeed we also had some questions regarding the true status of this issue. This is the reason why these issues are filed in a category called [PX] and the catalogue uses specifically the word ‘controversial’ to describe them (See also in Catalogue Vol I for the definition of [PX]).

It happens some time that even in case of same data and same design, stamps were issued by two countries with one denying the joint issue status. In fact, in almost all these cases, and this Japanese stamps probably included, a first contact between the authorities took place and topic as well as day of issue were agreed. But during the process, it came to a disagreement and finally each country decided to pursue on its own. For this reason, considering at least the situation of starting the collaboration, we report such stamps in the catalogue.

Obviously, it was not per chance that all four countries came together with Japan and launched almost at the same date each a stamp with the same topic (not the same design) also appearing on the Japanese stamps (relationship). We leave to the collector to decide if such items have to be include or not in their own collection. If these stamps are not described in the catalogue, other collectors would ask why such series are not reported. The [PX] status became the alternative. In any case, present or not in the catalogue, questions would arise. It is possible to definitely state about these Japanese stamps, if someone can bring the real story behind the creation of these stamps.

Can someone help here?

Poland – Slovenia 2023

Poland and Slovenia issued on March 6, 2023 identical stamps honoring Emil Korytko (1813-1839), a Polish ethnographer, exiled in Slovenia where he contributed to the translation of Slovene folk songs. Poland stamps became available in miniature sheets of 8 stamps [4×2] while Slovenia produced miniature sheets of 16 stamps [4×4]. The stamp represents a silhouette of Emil Korytko with handwriting in the background (information was first provided by Janko Stampfl, Slovenia).

Nicolaus Copernicus

The Stamp dedicated to Nicolaus Copernicus on January 29, 2023 by Poland has just to be considered as a lure for joint issue collectors ;-). In the meantime several friends from the Netherlands, Poland, UK and Italy provided information about the issue of the true joint issue related to the 550th anniversary of the birth of the astronomer Nicolaus Copernicus (Mikolaj Kopernik; 1473-1543). Both Poland and the Vatican State will issue on February 27, 2023 a souvenir sheet showing the painting “Conversation with God” (1872) from Jan Matejko (1838-1893) showing the astronomer surrounded by all his tools.

50 Years of Egyptian – Emirati Relations

Two flags, the figure “50” and a logo illustrate the common stamps of the EgyptUnited Arab Emirates issue celebrating the 50 years of bilateral relations between both countries. These twin stamps were released on January 19, 2023 in form of souvenir sheets with a single stamp. We are still missing details such as printing runs and size, but it seems these items are quite large (estimated 100×80 mm for Egypt and about 80×56 mm for UAE) (Information provided by Kenneth Sequeira, Singapore and Don Birschel, USA).


This issue has of course been added in the catalogue Vol 15. Some collectors asked for getting some details about the information updated in each catalogue when replacing a previous edition, as it is not obvious to see in a quick way what really was modified or added. We will try to supply this information whenever relevant at the end of a post like this one to help improving this identification. Here is the first set of information related to the modified content appearing in Vol 15 V4.02:

  • The new Egypt Emirati joint issue described above [T20230119]
  • Confirmation of the existence of mixed FDCs for the 2022 Romania – SMOM issue [N20220916], the mixed crypto stamp FDC from Austria and the Netherlands [T20220922], as well as for the older Colombia – Indonesia issue from 2020 [T20200915] (all mixed items produced and provided by Jaap sarelse – The Netherlands)
  • Introduction of the new Ecuador souvenir sheet in the joint issue [T20220728]
  • Update of the list of new issues to be released during 2023, mainly involving Morocco and Slovakia

Note that the page “Philatelic resources” is constantly updated to maintain the most accurate level (which is not easy, corrections and additions welcome) and changes will not be reported here.


Update: January 2023

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

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.

QEII commemoration

The postal administrations of Ascension Island, the British Antarctic Territory, the Falkland IslandsSouth Georgia and the South Sandwich Islands and Tristan Da Cunha have scheduled a joint commemoration of Her Late Majesty Queen Elizabeth II in the form of a set of two stamps in sheet format and one miniature sheet containing the two stamps from each territory. The initial press release indicates a planned release date of February 15, 2023 (information provided by Adam Paish, UK). It is to expect that around the anniversary date of her death, several countries will issue commemorative stamps. It is not unlikely that joint issues or at least common or borrowed design stamps could be created on that occasion and this one is just the first example.

Georgia’s diplomatic relations – 30 years

Georgia issued already stamps at the occasion of the 30th anniversary of its diplomatic relationship with different countries, first on December 7, 2022 with Azerbaijan, then on December 20, 2022, with Israel.

More recently, we learned from Kenneth Sequeira (Singapore) and Enzo Cafaro (Italy) that Georgia issued also one stamp identical to the Italy stamp itself issued on December 7, 2022. Date of issue of the Georgian stamp is apparently December 27, 2022, leading to a Concerted issue [C]. The only problem here is that despite the fact that the stamps are identical, Italian Post does not consider this issue as joint (???), at least it was not defined originally by an official decree. Fabio Bonacina (Italy) in Vaccari News, tries to give some explanations (https://www.vaccarinews.it/news/Dentello_pure_da_Tbilisi/33994). It is possible that Georgia produced their stamp on the basis of the Italian model once the Italian stamp was released, but up to the point to officially present pictures of both stamps, in a same room, on December 27, in presence of the Italian ambassador. In our case, it is clear that with such a similar design, the stamps must have been created on the basis of at least a limited initial collaboration between both postal administrations. Therefore, we will report this pair in the catalogue and I am sure, collector will be glad to have a funny story to tell behind these two stamps, despite the non-recognition of the joint character by one part. If we discover in a near future, another example of such (unilateral) twin stamps, we will probably have to create a new sub-type in our classification system.

Another astonishing point relates to the illustration. It represents the construction of the cathedral of Bichvinta, based on a design of Father Cristoforo Castelli (1597-1659). Bichvinta (also called Pitsunda) is located in Abkhazia, a territory that is under Russian control since 2008…

Arab League countries latest issues

Kenneth Sequeira (Singapore) was the first to discover and provide all pictures from the most recent GCC Arab countries stamps. Starting on December 12, the six countries Bahrain (), Kuwait (December 21), Oman (December 13), Qatar, Saudi Arabia () and the United Arab Emirates (December 12) issued the same souvenir sheet portraying the 6 Heads of States and a stamp showing the flags and one building from these states. These stamps were issued to commemorate the 40th anniversary of the Gulf Cooperation Council.

In a previous blog, we announced the issue of a common stamp created by the Arab Postal Union on the basis of a Qatar model to celebrate the FIFA Soccer World Championcup organized in Qatar. Only little information came through so far, but Mohamed Essawy (Egypt) and Ali Ahmed Med Achour (Algeria) could provide the first pictures of stamps from Jordan and Oman, apparently issued on December 18, 2022. We have to continue looking for similar stamps issued by other countries belonging to the Arab Postal Union, as this series is definitely not complete.

Georgia – Israel 2022

A Joint stamp was issued between Israel and Georgia in honor of 30 years of diplomatic relations on December 20, 2022 (information provided by Varda Lask, Israel, and Don Birschel, USA). The issue of the stamp is described in the Israeli brochure as follows:  ” The Umm Leisun inscription appears on an ancient Georgian tombstone made of limestone and is written in Georgian Asomtavruli script. It was discovered in 2002 during the excavation of a Byzantine-period Georgian monastery in the Umm Leisun neighborhood in southern Zur Baher, 4.5 kilometers south of the Old City of Jerusalem. The tombstone was found in an underground crypt beneath a colorful mosaic floor. The crypt contained 24 skeletons, all adult men, as would be expected in a monastery. The most important tomb has an inscription identifying it as that of “Georgian bishop Iohane”, the oldest monk, with the highest status. This inscription is the earliest known example of Georgian script found on any archeological artifact, both in the Holy Land and in Georgia. The inscription is engraved on the tombstone and measures 81 cm X 49 cm. It dates back to the late fifth or first half of the 6th century and is on display in the Knesset Archeological Garden. The full inscription reads: “This is the grave of Iohane, Bishop of Purtavi, a Georgian”. 

Latest news – December 2022

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.
