Unilateral issues update

The previous page on Unilateral Issues triggered a lot of answers leading to some new joint issues to be confirmed for the end of the year 2024.

Let us first start with the Kazakhstan – Morocco issue. A Kazakhstan stamp, in miniature sheets of 8 units, was released as early as September 30, 2024 with a topic related to the 30th anniversary of relationship depicting local Gastronomy (camel milk, kumis, dates), but above all with a stamp bearing the words “Joint issue Kazakhstan – Morocco”. Eventually, the Moroccan stamp was released on December 25, 2024, in sheetlet of 10 stamps. This issue can now be reported in the catalogue as a Concerted issue with the entry code [C20240930].

Similarly, the Egyptian counterpart for the Hungarian souvenir sheet issued on November 28, 2024, was discovered. We can therefore confirm that these two sheets from Egypt and Hungary form a joint issue that is described in the catalogue under the heading [T20241128]. The Egyptian souvenir sheet was issued at only 7,000 samples from which 700 were taken to prepare first day covers.

There is an interesting on-going discussion about a potential Italy – Peru joint issue related to the 150th anniversary of diplomatic relations between both countries. On August 28, 2024, Peru issued two stamps, so far without counterpart from Italy. In the 2025 Italian philatelic program, we discover now that Italy intends to issue stamps on January 30, 2025, celebrating the same event, but even claiming it should be joint. Italian Post just informed that there was a delay as they were not ready by the time of issue of the Peruvian stamps. As Peru issued their stamps unilateraly (without joint character claim), this announcement looks surprising. We have not seen the design of the Italian stamp and we will probably have to wait until January 30, 2025 to define the real characters of this stamp and decide afterwards how to consider them. There is one important point however to take in account: there should be no confusion between joint stamps and a joint event. So, decision to integrate these stamps in the catalogue, is still on hold.

The situation is clearer with the Peruvian – Dominican Republic issue. On November 13, 2024, Peru also issued stamps at the occasion of the 150th anniversary of the relationship between both countries. It appears that Dominican Republic issued a single stamp the same day, reproducing the buildings that are reproduced on the Peruvian stamps. In this case we are in presence of a real twin issue that will be described in the catalogue under entry number [T20241113]

In the meantime, a Mauritius – India mixed FDC became available. This item is based on an illustrated Mauritius first day cover celebrating the 200th anniversary of Maharishi Dayanand Saraswati (1824-2024), on which was added an India stamp with exactly the same design itself cancelled from December 12, 2024. By further inquiries about this document, Jaap Sarelse could confirm that this stamp release is not a joint issue. The design was made available by the Organization supporting the anniversary events, which any post office could use to issue a stamp. It happens that both countries used the logo alone to fill the space within the stamp which resulted to very similar items. Collectors created mixed FDCs only on the basis of the stamp similarities, but postal administrations never collaborated. Suriname issued also stamps at this occasion, using only the same portrait but not the full logo.


During this search activity, a new joint issue appeared that has been forgotten so far: Morocco and the United Arab Emirates celebrated historical relationship through identical stamps and souvenir sheets. These stamps were released on November 13, 2024. they represent symbols, flags of both countries, the “Hassan II” Mosque in Casablanca and the “Sheikh Zayed Grand Mosque” in Abu Dhabi.

For all this information, thanks to Ali Ahmed Med Achour (Algeria), Don Birschel (USA), Tolga Caglayankaya (the Netherlands), Enzo Cafaro (Italy), Fabio Bonacina (Italy), Kenneth Sequeira (Singapore), Jaap Sarelse (the Netherlands), Cesar Ittmann (The Netherlands), Eric Chan (Hong Kong) and Eric Contesse (France) through his Facebook blog Joint Stamp Issues (and of course all the collectors participating to this blog).

Unilateral issues 2024

By end of this year 2024, we have to come to the conclusion that some originally announced joint issues will probably remain unilateral, meaning that the partner country dropped from the collaboration. Here is the list:

  • India – Israel : 2024 (May 7) – Purim Festival -This stamp was originally scheduled to be released on February 13, 2024, but India was not ready to participate. The new date of May 7, 2024 was set, but the Indian stamp was still not available and information about the final decision from India is missing
  • China (PR) – Russia : 2024 (August 24) – Diplomatic relations – Panda. The issue was moved to August 24 from originally August 4, 2024, but no associated Chinese stamp was issued
  • Korea (South) – Uruguay : 2024 (September 10) – Uruguay issued two se-tenant stamps; [2px5] printed at 2,500 pairs, but no information is since available from South Korea
  • Kazakhstan – Morocco : 2024 (September 30) – Topic: 30th anniversary of relationship – Gastronomy. Despite the fact that the Kazakh stamp bears the words “Joint issue Kazakhstan – Morocco”, no information is available so far from the Moroccan side
  • Indonesia – Serbia : 2024 (November 4) – Topic: 70th anniversary of relationship – The Serbian stamp was issued, but no news from Indonesia

These stamps will remain in the catalogue with short description, with limited details and under the category ‘Unilateral – Not approved [N]’. THis is to avoid further questions in the future, but also as space-keeper in the case these issues transform into Delayed Concerted [C] issues during the year 2025.

An interesting story is linked to the expected Oman – Switzerland joint issue: On November 30, 2023, Oman and Switzerland were supposed to issue joint stamps celebrating the 50th anniversary of their diplomatic relationship. The Omani stamps were issued as expected, but Switzerland never made their stamps available, despite one existing copy in Oman Post Office archives, documented by the picture provided below and entitled “Celebrating 50 years of diplomatic ties between the Sultanate of Oman and the Swiss Confederation, we are pleased to announce the launch of the joint stamp. The stamp was launched under the patronage of Dr. Alain Berset, President of the Swiss Confederation, during his visit to the Sultanate of Oman.”(Information and pictures were provided by Tariq Al Lawati, Oman).

Through direct contact with the Swiss Post customer service, we received recently the following explanations : “I am pleased to inform you about the joint issue Switzerland-Oman. Unfortunately, the request from Oman for a joint issue arrived too late. Swiss Post nevertheless wished to support and pay tribute to this 50th anniversary of the diplomatic relationship. Therefore, Swiss Post has informed the Federal Department of Foreign Affairs (FDFA). A meeting with the Omani Embassy and Swiss Post regarding this matter has taken place, during which it was stated that an official stamp issue was no longer possible, but that we could offer a corporate stamp instead. The FDFA has expressly renounced any official issuing of the stamp.” Thanks to Ylenia Minesso, Swiss Post Customer Advisor, for this extensive answer. This issue will be reported in the catalogue, as mentioned above, with a short description and under the category unilateral.

A souvenir sheet from Iran appeared on the net. This item showing the Minsk City Gate and the Azadi Tower, dated 2023 (but issued August 22, 2024), includes the word “I.R. Iran – Belarus Joint Stamp”. No information is available from Belarus.

Two stamps from Laos, bearing the Laos and India flags were supposed also to introduce a joint issue, celebrating common cultural heritage. The Laos stamps and souvenir sheet were issued on August 15, 2024, but no information is available from the Indian side..

Peru released on August 29, 2024 a pair of stamp related to diplomatic links with Italy, and on November 13, 2024, a similar pair related to links with the Dominican Republic. No counterpart stamps have been seen so far from Italy or the Dominican Republic..

We are also waiting for the Egyptian counterpart of the Hungarian souvenir sheet (130×100 mm) issued on November 28, 2024 and clearly entitled “Hungary-Egypt Joint Stamp Issue”. Knowing the difficulty in obtaining information from Egypt, it may be possible that this souvenir sheet translates in a true joint issue. We still have to wait.

Same situation for the Serbian stamp, entitled “Serbia – Russia” and dedicated to Colonel Nicolay Raevsky, issued on November 18, 2024, without Russian counterpart so far. However Russian Post web site is usually up to date and we should have the information. This stamp may remain unilateral.

Any additional information or change to this list is welcome.

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.

Hungary – Luxembourg

100 years of diplomatic relationship between Hungary and Luxembourg were celebrated on March 12, 2024 with a joint souvenir sheet. These commemorative items feature two paintings by Mihály Munkácsy (1844-1900), one of Hungary, Dusty Country Road II (after 1874), and another of Luxembourg, Grazing Cattle Herd (1882), in recognition of the fact that the world-famous artist is one of the closest cultural ties between the two countries. Munkácsy’s wife was Cecile Papier from Luxembourg, with whom he lived near the Belgian border at Château de Colpach in Luxembourg. 

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.

Hungary – Thailand nightlights

Nightlights, river-front historic buildings, Grand Palace of Bangkok, the Chao Phraya River and the Royal Barge are depicted on the Thai left part while, the Buda Castle and the Danube appear in the Hungarian right part of these very nice stamps from Hungary and Thailand. The margin of the Hungarian souvenir sheet shows also the same main buildings at daylight. This joint issue was released on November 29, 2023, by both countries in form of souvenir sheets at the occasion of the 50th anniversary of their diplomatic relationship.

Update October 2023

Alike in 2022 [B20221009], UPU proposed a common design at the occasion of the World Post Day and interested countries could adapt and join. These stamps were discovered accidentally, when the first stamps issued by Egypt and Sri Lanka were released on October 9, 2023. This year only a limited number of countries did participate, but the list is not complete yet and we are expecting discovering more of them. The design shows handshaking in violet and the size and structure of the stamp is similar as the one issued last year. The different adhering postal administrations could adapt the size and the language. This is not a true joint issue, but it will be described in the catalogue under the category Borrowed design [BD]. Other countries such as Malaysia, Pakistan, Thailand, issued also one or two stamps at the same date, related to the World Post Day, with different designs. Those stamps cannot be considered as joint as they are just commemorating a same event.

From Enzo Cafaro (Italy): The ‘Endurance’ stamp series involving British Antarctic Territory, Falkland Islands, South Georgia and South Sandwich Islands and described so far under March 27, 2023 [D20230327] has in fact never been released and was postponed recently a new time. The description of these stamps had to be removed from the catalogue and is now available in the waiting list at the end of the catalogue.

Jaap Sarelse (The Netherlands) discovered a series of three Singapore aerogrammes belonging to the 1992 ASEAN series. This country issued these postal stationeries on top of the stamps they released the same day. Up to now, those items were not described in the catalogue and the update will appear under the heading [P19920808], year 1992, Volume 6. Thanks Jaap, for providing this missing information.

New information related to the Euromed 2023 issue [P20230710]: Jordan issued a 6-stamp sheetlet on September 10, 2023. (Source Jeff Courtright, USA). On October 20, 2023, Albania issued the 2022 (!) Euromed stamp [P20220711] (Source Enzo Cafaro, Italy).

From Adam Paish, UK: there is an unusual Guernsey Post Office stamp issue scheduled for release on November 3, 2023, a souvenir sheet which contains two stamps, one inscribed ‘Guernsey’ and the other ‘Alderney’, depicting their respective courthouses. It celebrates the seventy-fifth anniversary of the 1948 Transfer Agreement which saw Guernsey take over responsibility for most of Alderney’s public services. Stamps inscribed Alderney or Guernsey are valid on mail from all the islands of the Bailiwick: Guernsey (incorporating Herm), Alderney and Sark. This item will be considered as a Territorial Se-tenant issue [SD].

The first image of the Thailand stamp/souvenir sheet from the Hungary Thailand joint issue to be released on November 29, 2023 was presented. This issue will celebrate the 50th anniversary of the diplomatic relationship between both countries.
