UPU 150th anniversary

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.

India Romania 2024

On September 17, 2024, India and Romania came together to produce a twin issue at the occasion of the 75th anniversary of their relationship. The stamps are illustrated with traditional costumes from both countries. India shows the ‘Lehanga choli’ (female) and ‘Dhoti kurta’ (male) costumes, while Romanian issue represents popular costumes from the Bihor County. Information about Indian stamps remains limited so far. We just know that the stamps were issued in panes and as a miniature sheet with both se-tenant stamps. Regarding Romania, stamps were issued in two panes of 32 stamps (2x[8×4]), in two miniature sheets of 5 stamps with a label, the label representing the other stamp without denomination, and a souvenir sheet with both stamps. As usually with Romania, the number of issued stamps remains limited: only 775 pairs of miniature sheets (2×3,875 stamps) and 4,550 souvenir sheets were printed. The number of stamps issued in panes is also limited to 2×8,064 (meaning that only 252 pairs of panes were printed), from which 406 pairs were taken to create as many official FDCs.

This information was collected and provided almost at the same time by Madhukar Jhingan (www.stampsofindia.com), Kenneth Sequeira (Singapore), Souvik Ghatak (India) and Don Birschel (USA). Thanks to all of them.

Update February 2024

Several new information have been reported over the month of February 2024, some of them even contradicting previously announced issues:

The first and most intriguing is related to the India – Israel joint issue initially scheduled for issue on February 13, 2024. From Uri Barlev (Israel), we learned that everything was prepared by Israel Post Philatelic Service, including printing and cancelling FDCs for release on that date. For some mysterious reason, there was a dispute between Israel and India postal services concerning the date of issue. India Post announced that the issue date would be in the third week of March. Hence, Israel Post withdrew the issue and recalled all distributed material. The Israeli material will be distributed on a new issue date, apparently May 7, 2024, and it is not clear yet if new FDCs will be prepared or the precancelled February ones will be used. No additional information is available from the Indian side.

The April 25th 1974 event was the overthrow of the Estado Novo government in Portugal.  It led to the independence of Angola, Cape Verde, Guinea-Bissau, Mozambique and Sao Tome and Principe.  All those countries could have been part of the joint issue announced by Portugal. Very recently, it was confirmed that only Angola and Cape Verde will join Portugal in this new issue scheduled for April 2024. Exact date is not known yet, but it could indeed be the anniversary date of April 25, 2024.

Stefan Kepic, Slovakia discovered an additional 2022 October 9 World Post Day stamp with identical design issued by Guatemala on February 28, 2023 in miniature sheets of 10 stamps (now reported under [T20221009]).

Ehsan Mehmood (Pakistan) reported information about products linking Belarus and Pakistan celebrating the 30th anniversary of their relationship. Pakistan issued a stamp on February 3, 2024 while Belarus issued a postal stationery (cover) on March 1, 2024 with first day cancellation on March 4, 2024. Designs are different and there is no hint from both postal administrations that these products have been created jointly. Therefore and unfortunately we cannot recognize them as joint.

During the year 2023, PostEurop celebrated its 30th anniversary. Some countries had issued during the year stamps using an identical logo provided by PostEurop. Information was collected about such issues but we had to come to the conclusion that the countries having celebrated with stamps this anniversary have not done it in a coordinated way and therefore all these stamps cannot be considered as joint. For those still interested in these stamps, here is a list of countries having participated during the year 2023: Azerbaijan (July 10), Bulgaria (September 12), the Faroe Islands (October 23, logo on a stamp showing waterlilies), Kazakhstan (November 20), Moldova (May 20) and Serbia (September 5). The Isle of Man (July 5) added this logo on a their 2023 Europa stamp, while Poland (December 1) and Romania (August 31) have both issued a postal stationary. This list may not be complete and any additional information is welcome.

January 2024 News

Several friends provided interesting information over the past weeks:

Kenneth Sequeira (Singapore) discovered an item based on an older Indonesia souvenir sheet, originally part of the Indonesia – Thailand joint issue from May 5, 2016, overprinted at the occasion of the Philatelic Exhibition “Thailand 2023”, that took place between November 27 and December 2, 2023. This is not part of a joint issue, but as material from a previous joint issue was used, the item needs to be described under this heading [T20160505].

The 60th anniversary of the relationship between Tunisia and The People’s Republic of China was celebrated by Tunisia with a dedicated stamp showing a panda with a text in both Chinese and Arabic characters. Unfortunately China did not issue any counterpart philatelic material and this unilateral stamp will not be reported in the catalogue (information received from Med Achour Ali Ahmed, Algeria).

During its 44th session in Cairo (Egypt) on January 11, 2024, the Permanent Arab Postal Commission decided to issue by Arab member countries a postage stamp in solidarity with Gaza. A commission was set up to discuss its design. No release date has been brought forward (information received from Med Achour Ali Ahmed, Algeria).

The UPU has launched the campaign of its 150th anniversary, announcing a possibility for all voluntary postal administrations to participate on October 9, 2024 with a common stamp. The suggestion is to use the logo of the anniversary which has been shown at the end of last year. So far, more than 20 countries have confirmed their participation, but eventually about 200 countries could participate. As this issue is created upon a kind of central invitation, not printed centrally and as there is some freedom to adapt the logo, but with the suggestion to release them at the same date, this issue has to be considered as a true twin issue. It looks like a future omnibus series. There will be hundreds of products available and it could be understandable that some collectors will not consider integrating these stamps in their collection. The design of the proposed common stamp became available.

Enzo Cafaro, Italy, found information about the next India – Israel joint issue dedicated to Purim Festival to be released on February 13, 2024 and he could already provide the design.

All catalogue volumes have been updated and are available on line. The list of additional issues expected to be released during the year 2024 has been integrated in the catalogue Volume 15.

India – Oman 2023

A surprise joint issue was released by India Post and Oman Post on December 15, 2023, commemorating India and Oman’s friendship. The joint stamp depicts “Al Razha”, a traditional Oman dance form characterized by its graceful movements, intricate footwork and the use of swords. On the other stamp face, the Indian cultural dance depicted is “Dandiya Rass”, a popular folk dance from Gujarat, India, known for its energetic and rhythmic movements performed by both men and women in their native costumes using sticks. The stamps were released during the official visit of His Excellency Sultan Haitham bin Tariq to India (Information provided by Souvik Ghatak, India and Kenneth Sequeira, Singapore).

Update November 2023

A joint issue between Panama and the Sovereign Military Order of Malta (SMOM) was under discussion for a long time with proposals for issue dates fluctuating over the past months. Eventually, the stamps were issued. The SMOM stamps were released on October 26, 2023, which was also given initially as first day of issue for the Panama stamp. However, the official ceremony is now scheduled to take place in Rome on December 4, 2023, which could become the official date of issue of the Panama stamp as well, even if first day cancellations from October 26, 2023 have already been seen. We will need to confirm the first date of issue for both countries within the next days or weeks. At least, in the meantime, we can provide pictures of the stamps. SMOM has take the same design but, it was divided in three vertical stamps with quite a high denomination each. Thanks to Jaap Sarelse (The Netherlands), Enzo Cafaro (Italy), Eric Contesse (France) for information and exchanges over several months about this issue.

Following the large number of stamps issued at the occasion of the Tanzanian PAPU building inauguration (see previous post), almost the same countries (with stamps produced at the same central place) joined the World Post Day series issued on October 9, 2023 [B20231009]. To the original short list including Egypt and Sri Lanka, one has now to add the following countries: Central African Republic, Djibouti, Guinea, Guinea Bissau, Liberia, Niger, Sierra Leone and Togo. Each of these countries issued a stamp in miniature sheets of 8 stamps [4×2] and a souvenir sheet with a single stamp, all available as perforated and non-perforated products. On top of this, a miniature sheet of 4 pairs of se-tenant stamps including in the following order Liberia, Central African Republic, Guinea-Bissau and Sierra Leone was produced. In the same way described for the PAPU stamps in the previous post, the large number of products from these additional countries must also be considered as abusive, but these stamps will be reported in the catalogue for those collectors who are still interested.

From Uri Barlev (Israel): On December 12, 2023, a joint issue involving Israel and Guatemala will be released. The issue topic shows lakes, the Israeli Lake of Galilee (the Kinneret) and the Guatemalan Lake Atitlan. Uri was able to provide the first images of the Israeli stamp as well as the FDC. Thanks Uri.

At the beginning of the year 2024, China (PR), Hong Kong and Macau will celebrate the new year of the dragon with a se-tenant souvenir sheet [S] including four stamps from each postal administration (information provided by Wayne Chen, USA).

Additional news: following an exchange with the Hungarian Post, Kenneth Sequeira (Dubai) was confirmed of the cancellation of the Hungaria – India joint issue dedicated to the Art of Amrita Sher-Gil and initially scheduled to be issued during the fourth quarter of 2023.

The catalogue pages in Vol I and XV will be updated with all this new information within the next three days.

India – Mauritius 2023

The India – Mauritius joint issue related to the 75th anniversary of their diplomatic relations was initially announced to be released by August 15, 2023. Eventually, the stamps became available in both countries on November 2, 2023 (Source Souvik Ghatak, India). To commemorate this anniversary, a common stamp reproducing the national birds was produced in panes, but also as a souvenir sheet with a single stamp. For India, the blue peacock (Pavo cristatus) is shown, while Mauritius has the Mauritius kestrel (Falco punctatus) as emblem. The peacock had already been used as symbol of the country by India in two previous joint issues, with France in 2003 and with Papua Guinea in 2017. So far, only low quality images of this issue are available.

India – Vietnam, at last

The stamps were on a waiting list since April 28, 2023, and, finally, they became officially available on October 16, 2023. Since beginning of the year, the India – Vietnam joint issue went through several hickups starting with the isolated release of the Vietnamese stamps at a single postal office on the official initial April 28 date, but was quickly retrieved from sale after apparently 4,000 samples were sold. In the meantime, India announced several intermediate release dates until it came to a real availability this week (Information provided simultaneously by Kenneth Sequeira, Singapore and Souvik Ghatak, India). As a consequence of this earlier accidental availability, this series will be filed as concerted issue [C] rather than Twin [T].

These stamps celebrate the 50th anniversary of the diplomatic relationship between both countries, which actually goes back to January 7, 2022, with illustrations of local fighting sports. Vietnam introduces the martial art Vovinam and India introduces the martial art Kalarippayattu. The Vietnamese stamps are available in panes (total 5,400 sets), booklet of 4 pairs, imperforate stamps (1,800 sets) and specimen overprinted stamps (1,300 sets). India has released stamps in panes and souvenir sheets, but details are awaited.

Update June 2023

Jaap Sarelse (The Netherlands) informed us that the country Chad added stamps with the same design to the series of 2019 (October 9) stamps dedicated to Jerusalem – Al-Quds capital city of Palestine. Chad issued two stamps with denomination 150F and 400 F, but also a golden larger size stamp at denomination 1000F. These stamps were issued on November 30, 2022. 150F stamps were issued in sheets of 15 stamps, 400F stamps in sheets of 10 and golden stamps in miniature sheet of 4 stamps. All three stamps are available as imperforate and as postal stationery (postal cards). In the catalogue, only the three basic stamps are considered as real collectables, other products being just items to fool collectors. But everyone is free to add any product to his own collection.

The Sovereign Military Order of Malta (SMOM) was involved in the past weeks in two joint issues. The first one was issued on May 16, 2023, and involves the Vatican City. It celebrates the 825th anniversary of the dedication of the Cathedral Santa Maria Assunta in Spoleto. The second one was released on June 23, 2023, together with Slovakia and is dedicated to the humanitarian activities to welcome Ukrainian refugees. As SMOM is still not recognized by UPU, and as these two series are not involving a third country, these two joint issues are reported in the catalogue, but with heading Non-approved [N]. Again, collectors have to decide if they want to include these stamps in their collection. Catalogue are just there to indicate their existence.

By end of last year, regarding the philatelic year 2023, there was a high number of announcements of joint issues involving India. These issues should involve Israel (February, no news), Luxembourg (March 14, issued at the expected date), Hungary (2023), Vietnam (April 23, apparently stamps were printed, but only partly released in Vietnam and not seen yet in India), Mauritius (August 15), and South Korea (December 8). So this totaling up to 6 joint issues, but with only one released so far and all the others remaining questionable. Any help in getting information from India is highly welcome.

Don Birschel (USA) discovered this joint issue between Egypt and Kazakhstan, released June 4, 2023, and dedicated to the 850th birthday of Sultan Al Zahir Baybars (1223-1277). The common stamp represents a coin, a dinar minted during Baybars’ reign, bearing his blazon, the lion/panther. Kazakhstan issued a second stamp with the portrait of the ruler, in a diamond shaped miniature sheet including two se-tenant pairs.

The EuropaCEPT series issued on May 9, 2023 with common stamp “Peace” was completed with following countries: Kazakhstan (June 1, 2023), Georgia (June 16, 2023) and Isle of Man (July 5, 2023). The Isle of Man stamp with identical design is part of a series of 7 stamps celebrating the 50th anniversary of the Isle of Man postal administration. Only one stamp bears the PostEurop 30th anniversary logo, which is the one to be taken in account as part of this year series. The six other stamps show earlier stamps (stamps on stamp) among which some of them featuring Europa Cept and PostEurop stamps from years 1976, 1980, 1987, 1995, 2004 and 2023. The only stamp on stamp part of an earlier joint issue is the one representing the common design from 2023, together with three other stamps issued in 2023, probably the first example of a stamp on stamp issued the same day as the original stamp. Albania, Armenia and Azerbaijan remain on the waiting list and should be issued within the next months.

On June 18, 2023, Qatar and Georgia have released a joint (twin) issue at the occasion of the 30th anniversary of the establishment of diplomatic relations between both countries. The stamps feature landmarks (buildings, towers, sculptures) of the capital cities of Georgia (Tbilissi) and Qatar (Doha) (issue discovered by Enzo Cafaro, Italy). High quality image of the Qatar stamp is not yet available.

Update May 2023

Next to the large PostEurop series issued around May 9, 2023, a few other countries released joint issues:

The Belarus – Russia joint issue was released on May 13, 2023. They celebrate the 150th anniversary of the painter Stanislas Zhukovsky (1873-1944) under the form of a souvenir sheet from each country representing a different painting. The margin shows different portraits of the painter. As a consequence, this becomes a parallel issue [P1]. Belarus issued 10,000 souvenir sheets, but also 5,000 samples as imperforate, while Russia issued 20,000 souvenir sheets as well as 4,200 samples of a special folder containing the same souvenir sheet, imperforated.

Milan Csaplar (Slovakia) provided update about future joint issues involving Slovakia. The design of the Slovakia – SMOM issue became available and the stamps will be released on June 23, 2023. Reminder: as SMOM is not recognized by UPU and as no other country is involved in this issue, this pair will not be approved as joint, but still be reported in the catalogue for collectors of SMOM stamps. The design of the Joint Issue with the Czech Republic at the occasion of the 30th anniversary of the establishment of the Czech Post and the Slovak Post was also released. These stamps are supposed to be released on October 2, 2023.

Enzo Cafaro (Italy) provided information about a joint issue between the Sovereign Order of Malta (SMOM) and the Vatican City issued on May 16, 2023 and commemorating the 825th anniversary of the dedication of the Cathedral Santa Maria Assunta in Spoleto (1198). Stamps are identical and show the façade of the cathedral, also known as Duomo of Spoleto, and a fresco by Filippo Lippi dedicated to the Stories of the Virgin (15th century). However as SMOM is not recognized by UPU, this issue cannot be recognized as a true joint issue and will be reported in the catalogue for SMOM collectors but under the heading Non-accepted [N].

Vietnam appears also in two official joint issues, but information to complete these series is missing. We reported already the picture of the joint issue with India (April 23, 2023), but are still waiting for India’s counterpart. Uruguay announced and released a souvenir sheet related to the 30th anniversary of relation with Vietnam. Picture of the Uruguayan item released on April 27, 2023 is reproduced below, but no news is available from Vietnam.

Back to the 2023 PostEurop stamp issue, there is a clarification to make, following a note sent by Stewie Griffin: BeePost (actually very close link to Stamperija and Peterstamps, same office address) did not have the legal permission from PostEurop to print Europa stamps, nor to use the Europa logo and design. The BeePost stamps described in the previous Post related to Europa 2023 stamps must be considered as illegal and should not appear in a serious stamp collection. They will not be described in the catalogue either, when updated. Actually we learned also that BeePost’s website is now under “maintenance” and Stamperija removed all BeePost “stamps” from their website. Thanks for this information which details can be found under https://www.stampboards.com/viewtopic.php?t=100797

In the meantime additional stamps related to PostEurop Peace 2023 became available: Estonia (May 25, 2023, one stamp in miniature sheets of 10 stamps), Greenland (May 30, 2023, 2 stamps available in sheetlets of 10, but also in a booklet of blocks of 6 from each), Nagorno Karabakh now issuing stamps under the name of Republic of Artsakh (May 25, 2023, two stamps available in miniature sheets of 10, but also in a miniature sheet of 5 se-tenant pairs), and Belgium (to be released on June 12, 2023, but illustration already available; one stamp in a miniature sheet of 5 stamps). The illustrations of the stamps from Azerbaijan became also available, but the exact date of release (in June) is still not known.

In Denmark, the Europa stamp is presented in a form of a souvenir sheet including the common stamp and a second commemorating stamp representing a candle. This second Denmark stamp was originally issued in 1970 to celebrate the 25th anniversary of the end of WWII. On May 4, 1945, a candle was put at all windows in Denmark, when armistice was signed, and this tradition continues since, symbolizing peace. The stamp from the souvenir sheet is an adapted reproduction of the 1970 stamp, but the isolated candle stamp issued as self-adhesive in a miniature sheet of 10, does have a different design. Only this isolated stamp bears the sentence “Sammen for fred” (Together for peace), which appears actually in the souvenir sheet only on the common stamp.

At this stage, for this 2023 Europa series, we are still missing information regarding the participation of Albania, Armenia, Georgia, the Isle of Man and Kazakhstan.


Eventually catalogues have been updated. Of course Volume 15 contains all new data and stamps released during the past two months, but also information about some new mixed covers created by Jaap Sarelse (the Netherlands) that had not been reported so far. Volume 2 has been completed with the 1950 (April 12) Milan Trade Fair stamps. And of course, the Country and Topic pages of Volume 1 have been updated at the same time, the new sub-category [P3] is described.

2002 Japan joint issue revisited

For few months now, there is a discussion going on if the stamps issued in 2002 by India Post and Japan Post with the title “50th Anniversary of Diplomatic Relations between India and Japan” is really a joint issue or not. 

Our friend Souvik Ghatak (India) filed an application to India Post under the Right to information (RTI) act of 2005. He asked them, to confirm the joint issue status and to provide a copy of memorandum of understanding signed between both postal departments.

Indian Post provided the following information about the issue presently referenced in the catalogue under [P20020412a]: 1) This is not a joint issue and 2) since it was not a joint issue they could not provide a copy of memorandum of understanding between India Post and Japan Post (see copy of answer below). 

Thank Souvik for providing this information confirming this is not a joint issue. As a consequence, it will also apply to all other stamps issued on April 12, 2002 by Japan Post and involving Bangladesh [P20020411], Pakistan [P20020412a] and Sri Lanka [P20020412c].

Actually, in the catalogue, these issues appear already with the mention ‘controversial’ and the classification PX, which stands for doubtful. Accordingly, the wording in the catalogue will be modified and eventually these series will be switched from PX to N section. The stamps will remain described in the catalogue as numerous collector do own them already, but as for all the ‘N’ (non-accepted) joint issues, the collectors have to decide if they want to keep them within their Joint issue collection. The catalogue will just tell them the real status of these issues, which will now respectively be [N20020411] for Bangladesh-Japan, [N20020412a] for India – Japan, [N20020412b] for Japan – Pakistan and [N20020412c] for Japan – Sri Lanka.

Joint celebrations of diplomatic relationship does not necessarily mean that the stamps issued at this occasion are joint. The joint character comes from the will of both administrations to work together on a specific topic. Administrations define date of issue and design. However, even if discussions have started, administrations may finally decide that they will not issue the stamps jointly, resulting in absence of common stamps, no exchange of products, no common joint FDCs, etc. even if the topic remains the same.

There are several countries issuing regularly diplomatic relationship stamps without any connection with the other country. Brazil for example, is issuing several times a year, stamps related to other countries and very seldomly transforms them in a joint issue. These isolated stamps are not even to be considered as unilateral issue, as this vocabulary applies only in the case production of stamps eventually failed for any reason on one side.

Update April 2023

Don Birschel (USA) confirmed the existence of the Albania – Kosovo joint issue by providing the first picture of the Albania souvenir sheet. Unfortunately, so far no official information is available from the Albanian side. By exploring further, we found out that a cover looking like a first day and dated April 27, 2023 became also available on eBay. The Kosovo stamp was issued in miniature sheets of 4 on February 17, 2023. Even if this cover does not bear the words ‘First Day’, it could at least confirm that this issue must be considered as Concerted and not Twin [C20230217]. Any additional information is welcome.

Jaap Sarelse (The Netherlands) continues to create mixed FDCs and recently he was able to provide a mixed cover from the [C20221207] Georgia – Italy mixed first day cover and the one involving Armenia and Russia corresponding to the issue [T20220830].

We learned also that in 2024, at the occasion of the 150th anniversary of the UPU, a joint issue will be produced with an identical design (competition is open) and the date of this issue will probably be centered around October 9, 2024. Knowing the number of member countries of the UPU (192 so far), this could become the largest joint issue ever. Call to participant countries was launched.

Still waiting for news from the India – Vietnam joint issue supposed to be released on April 23, 2023 (local fighting sports. We just had access to the design of the Vietnamese stamps. Any additional information is welcome.
