Gaza, rivers and snake

During the month of December 2025, so, with one year delay, Saudi Arabia also issued a stamp relative to the Solidarity with Gaza set. This new stamp has to be added to the [T20241129] stamp series of the same design that already included Algeria – Djibouti (November 11, 2024) – Jordan (November 28, 2024) – Libya (December 31, 2024) – Morocco – Oman – Qatar (November 28, 2024) – Syria (October 7, 2024) and Tunisia. Details (including exact date of issue) for this additional country are still missing.

Similarly, Sudan released three stamps at the occasion of the Arab Postal day, with the same design as the stamps proposed on August 3, 2025 [T20250803] by seven other countries (Algeria – Egypt – Iraq – Libya (2025) – Oman – Tunisia (August 4, 2025) and the United Arab Emirates). Exact date of issue remains unknown for these three new stamps (difference can be seen only at the level of the denomination).

Regarding the previously reported joint issue between Laos and Thailand [T20251219], the stamps from Laos had not been shown yet. Here is a first illustration showing clearly the twin character. However, it is still not clear if Laos issued a second stamp similar to the second stamp from Thailand.

Egypt and Portugal celebrated 50 years of diplomatic relationships on December 18, 2025 with souvenir sheets containing each a pair of stamps representing the Nile River and the Douro River. Details from the Egyptian souvenir sheet are missing. The Portuguese souvenir sheet, size 95×125 mm has been issued at 20,000 samples only.

We got also some information about a potential joint issue involving Jordan and India for stamps supposed to be issued on December 16, 2025, but so far nothing could be confirmed and no stamps have been seen. Also, we are still looking for the illustration and exact date of issue of the Uruguayan stamp produced jointly with Romania and showing horses. Similarly, there are no news so far, from the Vietnam stamps supposed to be issued in parallel of Cyprus on December 1, 2025. Latest information seems to confirm that the Cyprus stamps could remain unilateral.

Thanks to Kenneth Sequeira, Dubai, and Jaap Sarelse, the Netherlands, for providing a large part of the information described in this page.

Horses, map and traditions

On December 5, 2025, Uruguay and Romania issued joint stamps at the occasion of the 90th anniversary of their diplomatic relations establishment. The commonly accepted topic was horse breeding illustrated by two stamps showing the Romanian Lipizzan horse and the South American Criollo horse. The Uruguayan stamps have not been seen so far, but their issue confirmed by an announcement describing a se-tenant pair of stamps printed at 2,500 samples in miniature sheets of 4 pairs (so, only 625 miniature sheets available). At the other end, Romania is still complicated in terms of proposing different sub-types and their limited number of prints. In this country the following items are available: the two stamps, issued in panes of 32, within which the next to last row is printed upside down to allow creating tête-bêche samples (printed 2×5,472 stamps, i.e., 2×171 sheets only – a part was taken to create first day covers), 2 miniature sheets with 3 stamps and one label at the top right position (122×91 mm – printed 2×1,550 miniature sheets), one illustrated souvenir sheet with a pair of non se-tenant stamps (120×164 mm – printed 3,150) and another illustrated souvenir sheet with the non-se-tenant stamps, same size, but imperforate and numbered, available only in a folder produced at 277 (!) samples.

The 40th anniversary of the relationship between Oman and Russia was finally released on December 10, 2025 (after 5 successive announcements of changes of issue dates). The issue initially intended to celebrate the Omani explorer Ahmed bin Majid and the Russian traveler Afanasy Nikitin, led finally to a common stamp showing an old map, taken from the manuscript Kharīdat al-ʻAjāʼib wa Farīdat al-Gharāʼib, or ‘The Pearl of Wonders and the Uniqueness of Things Strange’ (written 1419), by Oman scientist Umar ibn Muẓaffar al-Wardī (died 1447). In both countries, the stamps have been released as miniature sheets [3×3], containing 9 stamps for Oman, but with central label for Russia, so, only 8 stamps in the Russian miniature sheet. Oman released another souvenir sheet, showing the two explorers, with a perforation centered over the portrait of the Omani traveler. This item shows a design which could have been used by Russia, simply by shifting the perforations, but this was not translated in a Russian product. The choice of the map as common design, may also explain the delays, probably upon reluctancy of the Russian post to use the Omani proposal (which is not a standard Russian stamp printing form).

On December 11, 2025, Indonesia and Serbia surprisingly issued stamps to celebrate relationship illustrated with typical local houses and a couple dressed in local costume. For both countries, the stamps are issued se-tenant, in miniature sheets of 4 pairs.

The first images of the December 19, 2025, Laos Thailand joint issue have been made available, but details for Laos are still missing. The Thailand stamps were issued in miniature sheets of 5 se-tenant pairs, chessboard ordered.

We are still missing information from Vietnam about the joint issue with Cyprus issued on December 1, 2025. So far we had only access to the FDC cover from Cyprus.

Most of this information was provided by Kenneth Sequeira (Dubai) and Enzo Cafaro (Italy). Thanks to both of them.

September 2025 update

Sorry for this long time of silence. A lot of new information was gathered over this past month, in addition to the “Dove of Peace” series described in the previous page. The data are summarized hereunder, thanks to Kenneth Sequeira (Dubai), Ali Allawati (Oman), Adam Paish (UK), Enzo Cafaro (Italy), Dominique Josse (France), Sim Tng Kwang (Singapore), Mohamed Achour Ali Ahmed (Algeria), and Marci Jarvis (USA).

The official day of issue of the Oman stamp related to the Arab Postal Day from August 3, 2025, initially announced as being released on August 10, 2025 for this country, has to be corrected to August 3, 2025, according to FDC images provided by Ali Allawati.

The Oman stamps from the Oman Iran issue initially scheduled to be released on May 27, 2025, became available only on August 26, 2025 (date shown on the Oman FDC cover). However, information from Iran is still missing and we do not know if it will become a real joint issue, despite the clear indication on the stamp itself.

The Maldives-Singapore joint issue which design was revealed on June 30, 2025, was finally released on September 5, 2025. This issue includes two stamps featuring fishes, turtle, corals, the Lazarus Island (Singapore) and Hulhudhoo (Maldives), which were also included in a souvenir sheet (Singapore). Good quality images and final product description from the Maldives are still missing.

Singapore was involved a second time this month, on September 19, 2025, to celebrate the 60th anniversary of Thailand-Singapore diplomatic relations. As previously, Singapore issued also both stamps in a form of a souvenir sheet. The Thai stamps has been printed in se-tenant checkerboard-formatted sheets of ten stamps.

On September 16, 2025, the 640 years of the crowning of Sigmund of Luxembourg in Hungary was supposed to be celebrated by Luxembourg and Slovakia with a common stamp which design was released earlier this year by the Slovak Post. It happened that this issue disappeared from both postal administration philatelic programs. Explanations are needed here.

The Mythical heroes crypto-stamps series was issued on September 18, 2025 (see detailed description under previous page). The final illustrations given below show small changes compared to initial illustrations provided earlier (e.g., new denomination for Luxembourg). The series includes Austria (2 units, Zeus and Hera, 2×150,000), Belgium (Athena, 20,000), Luxembourg (Artemis, 15,000), Netherlands (Hermes, 25,000) and Portugal (Poseidon, 25,000). The digital twins are stored in the blockchain in five different colors. The likelihood of getting a particular color depends on the color: for Luxembourg stamps, there are 150 red, 1,005 yellow, 1,995 blue, 4,005 green and 7,845 black stamps; for the other countries the exact number of colored subtypes has not been published but the figures remain probably close to the same ratio, i.e., 1% (red), 6.7% (yellow), 13.3% (blue), 26.7% (green) and 52.3% (black). The digital twin of the crypto stamp is randomly generated. By scanning the QR code on the stamp with a smartphone, one will find out which color is linked to the crypto stamp.

As an example, the Luxembourg stamp digital twins in the blockchain look as follow:

On September 25, 2025, the Embassy of the Republic of Peru in Kuwait hosted an event to present a commemorative postage stamp marking the 50th anniversary of diplomatic relations between Kuwait and Peru. The postage stamps are featuring Kuwait’s Red Palace and Peru’s Real Felipe Fortress. Unfortunately, to our knowledge, this Peruvian stamp will remain unilateral.

The Oman-Russia joint issue, originally scheduled for April 22, 2025, postponed to September 26, 2025 (Oman source), then, a few weeks ago to October 15, is now scheduled for November 14, 2025. The date of October 15, 2025 remains unchanged for the issue of the joint stamps involving Laos and Russia and the first illustration of the Russian stamps became available recently.

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.

Mid Summer 2024 update

On August 8, 2024, the ten ASEAN countries decided again to issue jointly stamps (previous ASEAN joint issue goes back to 2019). Don Birschel (USA) provided the images of the first released ASEAN stamps and featuring general post offices. So far, the following country stamp images became available: Indonesia, Malaysia, Myanmar, Singapore, Thailand and Vietnam. The four other countries, Brunei, Cambodia, Laos and the Philippines are also supposed to have participated, but information is still missing at this stage.

Ali Ahmed Med Achour (Algeria) provided the following information: On the sidelines of the 45th session of the Permanent Arab Postal Commission held on July 18, 2024 at the headquarters of the General Secretariat of the Arab League in Cairo (Egypt), the Commission responsible for choosing the design of the “Unified Arab Stamp” dedicated to Gaza delivered its verdict. The model presented by Jordan will illustrate this stamp to be released this year. No specific issue date was lilinked to the issue so far. The countries that participated in this competition included Algeria, Egypt, Iraq, Jordan, Libya, Morocco, Oman, Palestine and Qatar.

The title of this issue will be “Solidarity with Gaza”. Its issue will coincide with the International Day of Solidarity with the Palestinian People established by the United Nations. It is generally held on November 29 of each year to mark the anniversary of Resolution 181, which is the Partition Plan for Palestine.
The 2024 philatelic program published at the beginning of the year by the Algerian postal administration has already selected this date of November 29, 2024 for the release of this joint issue. The list of countries that will participate to this issue is not known, but probably at least all countries having participated to the design competition will release a stamp. This issue will definitely become a twin omnibus series. The picture of the winning design is provided below.

The Grenada – South Korea joint stamps celebrating the 50th anniversary of relationship were issued as scheduled on August 1, 2024. The identical pairs of stamp show the Marryshow House in St George’s, Grenada and the Jibokjae Hall (library) at Gyeongbokgung Palace, Seoul, South Korea. Se-tenant stamps were released in miniature sheets of 8 pairs, chessboard ordered.

The China (PR) – Russia joint issue scheduled for August 4, 2024 (pandas) will in fact be released on August 24, 2024.

The Japan – Turkey joint issue scheduled for August 8, 2024 was released on that date in form of a single stamp for Turkey and a miniature sheet for Japan, with different designs.

All these new data have been integrated in the catalogue. Vol 1 and Vol 15 have been updated.

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.

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.

Poland Thailand 2022

The 50th anniversary of relationship between Poland and Thailand was celebrated as expected with a joint issue released on November 14, 2022. Both countries produced a similar miniature sheet containing four pairs of identical stamps showing the Palace on the Water in the Royal Łazienki in Warsaw, Poland and the Aisawan Thipphaya-Asana (called the Floating Pavilion) in the Royal Palace complex of Bang Pa-In, Ayutthaya Province, Thailand. Stamps were printed at respectively 120,000 (Poland) and 250,000 (Thailand) pairs.

World Post Day 2022 (2)

October 9, 2022, day at which the UPU organized a common issue at the occasion of the World Post Day, was a Sunday. This is not the best day for launching a stamp and we preferred waiting a few days to collect a maximum of information around this issue in order to include also stamps that were released after this official date. We were not disappointed and we received a lot of additional information from our friends Kenneth Sequeira (Dubai), Ali Ahmed Med Achour (Algeria), Don Birschel (USA), Enzo Cafaro (Italy), Kenneth Sequeira (Singapore) and others. Thanks to all of them.

So far (the list is probably not complete), the countries having issued stamps with the UPU design include the followings: Belarus, Bosnia Herzegovina, Cambodia, Croatia, Egypt, Fiji (September 22, release date, but official FDC dated October 9), Russia (October 7), Serbia (October 7), Sri Lanka, , Syria (1 stamp, 1 souvenir sheet), Thailand, Tunisia, Turkey. All these countries have issued one single stamp at the date of October 9, 2022, except otherwise stated.

Algeria (October 9, 2022) participated as well but adapted the design.

Latest information

Over the past two weeks, we got from different collectors several interesting information that are worth adding in the catalogue.

Saravanan (India) was the first to provide information about the recently issued stamps from Serbia, which are announced to be joint with Iran. Serbia issued a souvenir sheet with two stamps on September 30, 2022. So far, we have not seen any confirmation from Iran, but the Serbian stamps clearly state this relationship..

The announcement by the UPU of the issue of a common stamp at the occasion of the World Post Day on October 9, 2022 (see previous article) triggered also some interest from first countries.

Enzo Cafaro (Italy) was able to provide images from Belarus and Croatia, while StanD brought information out of Thailand. More information is needed but it seems this issue may unexpectedly become quite large.

Don Birschel (USA) discovered that the Laos stamps used at the occasion of the Tiger Forum (joint organized by Russia) on September 5, 2022, actually bear the logo of this Forum, on the contrary to the pictures we have shown so far. As we have not found the first stamps in previous issues, we have to consider that the first pictures without logo were simply early design proposals. Up to now, we got also the information that these both stamps were issued on September 1, 2022. This needs also to be confirmed. Any Laos-located collector to provide more data on this topic ? We are also missing information from Nepal that was supposed to take part to this issue. Any complementary information is welcome.

All the information collected over the past month has now been integrated in Vol 15 of the catalogue. Unfortunately, regarding the stamps that were announced to be released during the month of September 2022, we have no news from the Armenia- Bulgaria issue (probably cancelled), the Singapore – Ukraine issue (also probably cancelled), the Mexico – Vatican issue (initially scheduled September 21, 2022, but no information available) and the China – Japan issue (Japanese stamp issued, probably unilateral).

Pakistan -Thailand 2021 last minute

Don Birschel (USA), Kenneth Sequeira (Dubai) and Adam Paish (UK) provided at the same time the latest information of the year 2021 from Pakistan which devoted on December 31, 2021 a stamp related to the 70th anniversary of the relationship with Thailand. Two stamps have been issued in panes of 20 se-tenant pairs and represent Buddha heritage. Actually, these stamps are joint of identical stamps issued by Thailand on November 15, 2021 and that remained unnoticed so far. Thailand issued miniature sheets of five pairs of se-tenant stamps. as such, this joint issue is reported in the catalogue (Vol XIV) as a concerted issue [C20211115].
