Arab League, Euromed updates and others

by Richard Zimmermann

The following provides some information to complete description from issues released over the part couple of yeras and provided by friend collectors.

Kenneth Sequeira (Dubai) discovered a new stamp from Iraq to be added to the 80th Arab League anniversary series issued on March 22, 2025. The stamp is available in panels of 4×6 stamps and officially cancelled covers were also produced, but those do not show a date. We do not know the exact date of issue of this stamp, but of course it has been integrated in the catalogue. As 22 countries are members of the Arab League and as so far, only 10 countries have issued a stamp in the frame of this anniversary, it can be expected that other countries can be discovered as having participated. In particular, philatelic programs for Bahrein, Jordan or Oman, which are used to participate to such anniversaries, should be explored. Thanks for any feedback.

The Azerbaijan souvenir sheet, counterpart of the Türkiye souvenir sheet from June 10, 2026, appeared on Delcampe. At this stage we are missing the exact date of issue, but there are great chance that it could be the same as for Türkiye. For that reason, this issue remains filed as a Twin issue [T]. The two souvenir sheets are identical, but with mirrored illustrations.

A Mauritania – Morocco joint issue was supposed to be released on June 23, 2026. Eventually, the stamps from Morocco became available on July 29, 2026 and the Moroccan description notice is stating that this would be the second North-African joint issue involving Morocco, confirming indirectly the participation of Mauritania. Unfortunately, so far, no information is available from the Mauritanian side. The Moroccan stamps issued in se-tenant pairs and in miniature sheet of 5 pairs represent the City of Aït‑Ben‑Haddou Ksar, Morocco and the Chinguitti Mosque, in the capital city of the Adrar Wilaya, Mauritania. Both sites are listed as UNESCO world heritage (information provided by Roland Montagne, France). Any additional information is welcome.

In the frame of the Euromed stamp series dated July 13, 2026, Jordan issued three stamps in a same souvenir sheet as well as a non-perforated smaller souvenir sheet. Actually, in parallel, it was discovered that Jordan issued also four different illustyrated postal cards (postal stationery). These products have been added to the catalogue (Information provided by Fabio Bonacina, Italy, and Med Achour Ali Ahmed, Algeria).

We are still missing information about Albania and Egypt, two countries that were supposed to be involved in this same 2026 Euromed series. At the level of the 2026 Europa stamps we are also missing information about Albania, as well as Ireland (but this one is supposed to be issued by September 10, 2026).

Update August 2026

by Richard Zimmermann

The Croatia – Spain stamps that were originally announced to be issued on June 18, 2026, were finally released on August 10, 2026. They show two types of sailing boats (Betina – Crotia and Baleares – Spain). The Croatian stamps were issued in miniature panes of 6 pairs [2px3]. Spanish stamps were printed in panes of 14 pairs, i.e., [3px5] with the central pair replaced by two labels with flags.

The France – Thailand twin issue was released as announced on August 28, 2026, with general sale at post counters in France on the following Monday, August 31, 2026. The stamps represent the Eiffel Tower and the Seine River in Paris and the Wat Arun Tempel and the Chao Phraya River in Bangkok. Thailand stamps are produced in miniature sheets of 5 se-tenant pairs (printed 65,000 pairs), while French stamps became available in two miniature sheets of 10 stamps each (printed 2×350,000 stamps. Additionally, France released also a souvenir sheet of 200×90 mm containing both French stamps, produced at 15,000 samples.

The postal administrations of Ascension Island, South Georgia and the South Sandwich Islands and Tristan da Cunha have teamed up once again with a joint stamp issue reminiscent of that issued by these territories in November 2021.

The commemoration of the tenth anniversary of the United Kingdom’s Blue Belt Programme includes four stamps from each territory: these are issued both in individual sheets of ten stamps with a white edging and as souvenir sheets (with the design bleeding into the sheet border). This design is very close to the 2021 issue. The release date is scheduled for September 9, 2026. The territories currently involved in the initiative on top of the three countries listed above include Saint Helena, British Antarctic Territory, British Indian Ocean Territory and Pitcairn Islands. Additional participation from some of these countries could be announced within the next days or weeks but nothing has been published so far (information provided by Adam Paish, UK).

June 2026 update

by Richard Zimmermann

On June 12, 2026, Serbia and Slovenia issued a similar souvenir sheet containing one single stamp entitled “Humanitarians, Queen Marija Karađorđević and her court lady Franja Tavčar”. The Serbia souvenir sheet, 100×67 mm, was issued at 10,000 samples while the Slovenian souvenir sheet was printed at 18,000 samples. (Information was provided by Janko Stampfl, Slovenia).

Russia and the Philippines celebrated their 50th anniversary of diplomatic relationship on June 2, 2026 with an issue on June 18, 2026 of stamps representing fauna: the Russian Greater jerboa (Allactaga major) and the Philippine mouse deer (Tragulus nigricans). To date, no information from the Philippines postal administration is available, but Enzo Cafaro (Italy) was able to provide a copy of the Philippines miniature sheet, confirming that it could translate in either a twin or a concerted issue. Any additional information is welcome.

Moldova and Romania celebrated the centenary of the first flight of the Bucharest – Galați – Chișinău airmail service, illustrated by a Haviland DH-9 plane. This is a nice twin issue released on June 24, 2026. Romania released two stamps, showing either a plane over a landscape with a bridge (design A), or a flying plane, next to the names of the three towns from the airmail line, as well as a cancelled cover (design B). These two stamps were issued in panes of 32 stamps, or in miniature sheets of 3 stamps and a label. Additionally, a souvenir sheet with a single stamp showing the design A, with flag, cancelled cover as well as a black and white photograph became also available. Moldova released the same two stamps A and B in miniature sheets of 8 stamps (with two additional labels) and a souvenir sheet containing the design B, together with a map.

Note that 2×3,200 Romanian stamps (A and B) were printed in panes of 32 stamps, i.e., in 2 sheets showing 4 lines of 8 stamps. The third line was intentionally printed upside down, making possible to create 8 pairs tête-bêche out of each each pane. These printed stamps represent only 100 panes of 32, from which a maximum of 2×8 tête-bêche pairs could have been isolated, resulting in a maximum of 2×800 tête-bêche pairs possible. The real number of tête-bêche pairs will definitely remain far below that figure.

On June 10, 2026, Türkiye issued a souvenir sheet showing the portraits of Yunus Emre (1240-1320), Turkish folk poet, and Hakani-I Sirvani (1126-1199), actually Afzal al-Dīn Badīl ibn ʿAlī ibn ʿOthmān, commonly known as Khāqānī, Persian poet, entitled ‘joint issue with Azerbaijan‘. Unfortunately, by the time of publishing this page, no information has been made available from this country.

The situation is similar with a joint issue involving Morocco and Mauritania, which illustration was provided by Eric Contesse (France). On the Moroccan stamps, it is clearly stated that it is a joint issue. These stamps are also supposed to be released during the month of June and information from Mauritania is missing so far.

Another Türkiye – Romania joint issue was announced in the Türkish philatelic program, expected to be released on June 30, 2026, but no counterpart is mentionned in the Romanian philatelic program. On the other hand, Romania still describes a joint issue with Kazakhstan scheduled for June 2026 (Biosphere reserves), but there are no news that came up recently from both countries about this issue.

The first year of office of the Pope Leo XIV announced originally by the Vatican State as a joint issue with Italy, was eventually reduced to an anniversary issue from Vatican alone, on May 8, 2026, and this entry had to be removed from the poten,tial 2026 issues.

All the above news were introduced in the catalogue which is now available in an updated form in the appropriate section.

April 2026 News

by Richard Zimmermann

Adam Paish (UK) did send a first complement of information relative to the 100th anniversary of QEII described in the previous page and involving the British Overseas Territories : “The enterprising Isle of Man Post Office is no doubt anticipating another profitable venture with the release of a pair of Queen Elizabeth II Birth Centenary stamp sheets, one featuring previously-issued Isle of Man stamps, the other incorporating a selection of the British Overseas Territories stamps with royal portraits by Marcus Adams (Ascension Island, Bahamas, Falkland Islands, South Georgia and the South Sandwich Islands and Tristan da Cunha) and one commemorative stamp, repeated twice, from the Isle of Man itself. The pair of sheets is being marketed as a “limited release collectable” at GBP35.00, and the image has been provided by the Isle of Man Post Office for illustrative purposes only.  The Isle of Man stamp is one of a series of six celebrating the Fashion Legacy of Her Majesty Queen Elizabeth II, with the 93 pence denomination (based on 1941 portrait by Marcus Adams) reworked to fit into this multi-territorial commemorative sheet. The sheet concept is not dissimilar to the Devoted to Your Service souvenir released in 2021 to mark the late Queen’s 95th birthday which is illustrated in your 2019-2021 catalogue”

With the release of this souvenir sheet containing 12 stamps, i.e., 2 stamps per territory taken from the original blocks of 4 miniature sheets, this issue becomes a se-tenant series. However, this does not change the omnibus character and these stamps will remain being considered as non-approved joint issue [N]. Date of issue is April 21, 2026.

On April 27, 2026, Japan and Singapore will release a twin issue to celebrate their 60 years of relationship. To honour this journey, stamps features both national flowers: Japan’s cherry blossom and Singapore’s Vanda Miss Joaquim (orchid). Japan will release stamps in miniature sheets containg 5 of each of the stamps and produced at 400,000 samples (total of 4,000,000 stamps. The stamps of Singapore are available in miniature sheets of three pairs, but also in a souvenir sheet containing a pair of stamps.

A surprise came from Iran, a country presently in war, which finally released a stamp that was supposed to be joint with the pair of stamps issued by Oman on August 26, 2025. The exact date of issue of the Iranian stamp remains unknown, but it appeared at the beginning of April 2026 and became available in sheets of 8 stamps [2×4]. This series can now be attributed the entry code [C20250826] and is described in the 2025 year catalogue page (Information provided by Kazem Alamdari, Iran).

On the other hand, we are still missing information about potential counterparts of the Uruguayan diplomatic relationship stamp with Mexico (Uruguay stamps released on March 26, 2026), while the joint issue announced between Indonesia and Uruguay for March 30, 2026 has not been released. Also, it seems that the Laos stamp issued on March 20, 2026 celebrating the 70 years of relatioship with India will remain unilateral. Any additional information from these three countriues is welcome.

Horses, map and traditions

by Richard Zimmermann

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.

October 2025 News

by Richard Zimmermann

First of all, we have to thank Kenneth Sequeira, Dubai, who discovered a China PR-Indonesia joint issue from August 30, 2025, that we completely missed. This twin issue celebrates the 75th anniversary of relationship between both countries and is illustrated with landscapes of lakes and pagodas: the West Lake with Jingzi Tempel in Hangzhou, China PR and Lake Bratan with the Pura Ulun Danu Beratan, Hindu tempel in Bali, Indonesia.

The Bosnia Herzegovina (Bosnia) – Indonesia joint issue was finally relased on October 3, 2025. This issue was originally scheduled to be released on October 4, 2024, but was finally postponed by more than one year. The stamps issued in miniature sheets of two se-tenant stamps represent the Istiklal Mosque in Jakarta, Indonesia, and the Istiklal Mosque in Sarajevo, Bosnia. The Indonesian souvenir sheet is available perforated and imperforate. The word “Istiklal” in Arabic stands for ‘Independence’. The Jakarta Mosque was opened in 1978. The Sarajevo Mosque was a gift from the Indonesian people and Government of Indonesia for Bosnia and Herzegovina as a token of solidarity and friendship between the two nations. This Mosque was opened in 2001 (Information provided by Kenneth Sequeira, Dubai)

On October 7, 2025, France and Japan celebrated the Week of Letter Writing with a twin issue depicting gardens. On one side the French Vaux-le-Vicomte castle and gardens were represented, on the other one, the Gingaku-ji tempel or Silver Pavilion near Kyoto, Japan, was shown. France issued the stamps in two miniature sheets of 10, while Japan produced a single miniature sheet with 5 se-tenant pairs. Mixed official first day documents and a mixed folder with all four stamps, mint, became also available (This information was first provided by Dominique Josse, France).

Mongolia and India celebrated on October 14, 2025, the 70th anniversary of their diplomatic relationship with identical souvenir sheets containing two stamps showing the Mongolian Biyelgee dance and the Ramlila theatrical performance (India). The margins show both national flags, the anniversary logo, national animals (horse and elephant), folk arts, Mongolian ger (yurt) and the blue sky (information provided by Kenneth Sequeira, Dubai, and Robert Schrijvers, Mongolia).

China (PR) and Monaco are celebrating the 30 years of diplomatic relations (1995-2025) on October 15, 2025, with two stamps showing identical flowers, i.e., Canterbury bells, Campanula medium and an orchid, Cymbidium.

The Cat stamps related to the Laos – Russia joint issue from October 15, 2025, were presented in the previous page. Kenneth Sequeira was able to provide the illustration from Laos which is producing both perforated and imperforate stamps and souvenir sheets. The stamps show the Marbled cat (Pardofelis marmorata) and the East Siberian lynx (Lynx lynx wrangeli). Russian stamps are self-adhesive, sold in miniature sheets of 4 pairs, chessboard ordered. Laos stamps are available as perforated or imperforate souvenir sheets containing the pair of stamps.

The Gibraltar – Liechtenstein issue announced for December 2025 will in fact be released on November 10, 2025. It design is already available on the Liechtenstein postal administration web site (information provided by Kenneth Sequeira). Surprisingly this issue will be available in form of two souvenir sheets containing each a stamp from each country (different stamp designs), which defines this issue as Se-tenant joint issue [S2]. Stamps show falcons and are dedicated to the migration of these birds. Stamps are also available in sheetlets, and mixed FDCs are available.

Catalogues Vol 1 and Vol 16 have been updated with all this information covering the months of September and October 2025.

September 2025 update

by Richard Zimmermann

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.

August 2025 News

by Richard Zimmermann

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

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

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

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

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

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

Arab Postal Day 2025

by Richard Zimmermann

On August 3, 2025, Arab countries join to celebrate the Arab Postal Day with a stamp showing an identical design ‘Towards more innovative postal services’. So far, this issue involves Algeria (August 3), Iraq (August 3), Tunisia (August 3), and United Arab Emirates (August 3). More countries will probably be added (Information provided by Mohamed Achour Ali Ahmed, Algeria and Kenneth Sequeira, Singapore).

Additionally to earlier information related to the 80th anniversary of Arab League [T20250322], Kenneth Sequeira (Singapore) informed us that Sudan issued three stamps with three different denominations, not a single one as previously announced.

In the meantime, Qatar became also another country to be added to this series. The stamp was issued on June 15, 2025. There are still some chances that additional Arab countries will have to be added to this series.

June 2025 news

by Richard Zimmermann

Complementary information came from diverse collectors over the past three weeks. They are reported here, without any sense of priority.

Wayne Chen (USA) came across a vast number of se-tenant sheets fabricated and sold by Stampera. The full list is available through the companies’ site using the search tool and the word ‘siamese’ (reminder: in the joint issues definition, this word has to be replaced by ‘se-tenant’) https://stampera.eu/stamps?search=Siamese&page=1. As mentioned several times in the past in these pages, products released by this company are true stamps, but produced only for collectors in small amounts, without topic related to the country, and at a very high number of sub-types (souvenir sheets, miniature sheets, perforated and not) also with very high denomination. They are not called cinderellas, just because they show a denomination. A collector who wants to buy the complete set of these ‘se-tenant’ products (35 different products have been identified so far) will have to spend at least € 1,900 (souvenir sheets, perforated and non-perforated, both mint or FDC, without taking in account individual isolated stamps). All these products are simply made to fool collectors and cannot be approved as true joint issue. With the new printing technologies, they are also suspected to be printed upon demand only, i.e., sheet by sheet, so there is no limitation in terms of printing runs. In this case, they will not be reported in the catalogue, but we wanted to bring this information to your attention.

All described products have been printed by associating in a same miniature sheet, stamps from up to 6 different countries, available normally in panes. Some examples are provided below.

Robert Schrijvers (Mongolia) talked with Mongol Post about the potential joint issue between India and Mongolia intended to celebrate the 70th anniversary of diplomatic relations (December 1955 ?). These relations were initiated on December 24, 1955. Robert has seen the Mongolian version, but was not allowed to take a picture. It depicts Mongolian (biyelgee) and Indian dances. Decision to release and date of issue are pending upon Indian Post agreement.  

Milan Csaplár (Slovakia) provided the design of the joint issue to be released in August 2025, by the Slovak Post and the Luxembourg Post, which is dedicated to King Sigismund of Luxembourg (640 years of the crowning of Sigmund of Luxembourg in Hungary).

Ali Allawati (Oman) points to an error in the catalogue regarding the image of the Oman stamp from the Oman–Singapore joint issue [T20250221]. This mistake appears in both the blog and the catalogue.
The image of the stamp currently shown is taken from the souvenir sheet, which does not display a denomination. The actual stamp is priced at 500 Baisa. The stamp on the souvenir sheet does not display a price. The souvenir sheet price can be seen in the bottom left corner of the souvenir sheet. Below, in the reproduction, you can see the differences between the two stamps, the second one taken from the souvenir sheet, next to the complete souvenir sheet with denomination in the margin. This mistake was corrected in the catalogue. Thanks Ali. 

Ali provided additionally, a corrected version of the image used for the Oman–Iran joint issue from May 27, 2025. In the previous blog page, the illustration contains an error at the level of the title at bottom right, in which ‘Grand’ was mistakenly spelled ‘Ground’. This is corrected in the final version and to our knowledge, no stamp with the mistake was released. Both souvenir sheets (design left with mistake and final, corrected, right) are reproduced below.  We are still missing information from Iran.

On the other hand, we are also waiting information about the Oman – Russia joint issue announced in the press for a release on April 22, 2025.

Kenneth Sequeira (Singapore) found the design of the next Peru –Türkiye joint issue to be released in the second half of 2025, to commemorate the 75 years of relationship. No idea if both stamps will show the same design.

The issues involving Bosnia Herzegovina (Croatia) and Bosnia Herzegovina (Serbia) commemorating the 150th anniversary of the Herzegovina uprising, translated in two different stamps, issued at two different dates respectively June 15 and June 19, 2025, but above all, without any joint character, i.e. not claimed as joint by the two postal authorities. These stamps are to be considered as a simple anniversary commemoration, around the same date, and will not be included in the catalogue.

The catalogues Vol 1 and Vol 16 have been updated accordingly.

Arab League 80th anniversary

by Richard Zimmermann

The Arab League was formed in Cairo on March 22, 1945, and at the occasion of the 80th anniversary, the General Secretariat proposed a joint stamp issue based on a common design. Three countries, Algeria, Egypt and Tunisia issued a stamp on March 22, 2025. The design shows the logo of the League, a large figure “80” and the building of the headquarters in Cairo, Egypt.

The League was initially formed with seven members: Egypt, Iraq, Transjordan, Lebanon, Saudi Arabia, Syria, and North Yemen. Currently, the League has 22 members, i.e., Algeria, Bahrain, the Comoros, Djibouti, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Mauritania, Morocco, Oman, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, the United Arab Emirates and Yemen, which all of them could theoretically participate to this joint issue. Information from the other 19 countries is awaited, not necessarily with a date of issue of March 22, 2025. Thanks to Med Achour Ali Ahmed (Algeria) and Kenneth Sequeira (Singapore) who provided the first information and pictures related to this issue.

March 2025 update

by Richard Zimmermann

Kenneth Sequeira (Singapore) provided the first illustrations of the stamps and miniature sheets issued by the Sultanate of Oman and the Republic of Singapore celebrating their relationship established on February 21, 1985. The stamp features Muscat Street in Singapore’s Kampong Glam district, reflecting both Singapore’s heritage and its connection with Oman, through architecture and wall paintings. The stamps and souvenir sheets were released on February 21, 2025.

In the meantime, Estonia, Latvia and Lithuania issued similar stamps related to the integration of the Baltic States to the European electricity network. These countries disconnected their electricity grids from the old Soviet-era system (BRELL), which linked them to Russia and Belarus, and synchronized it with the European grid (ENTSO-E) on February 9, 2025. The project involved building new infrastructure, upgrading power lines, and installing synchronous condensers to stabilize the grid. The stamps were issued on March 7, 2025. The three stamps are not identical, but very similar, created by the same designer and considered as twin stamps of type [T3].

Kenneth Sequeira (Singapore) provided a series of information about new issues to be released during the year 2025. In particular, Indonesia made a series of announcements of joint issues related to diplomatic relationship with Russia (February, 2025), China PR (April), Serbia (August), and Bosnia Herzegovina (September or October 3). Knowing the broad definition by Indonesian post for joint issue, we will have to wait for announcements and even release of stamps from the partner countries before confirming existence of these issues. In particular, we are already missing information about the supposed to be released February issue with Russia (no information in the Russian philatelic program).

A Portugal – India diplomatic relations joint issue was also announced to be released on April 7, 2025. On the other hand, the long awaited UNESCO Intangible Cultural Heritage joint issue between Azerbaijan and Kyrgyzstan, telling tradition of Nasreddin Hodja anecdotes, is finally cancelled, without explanations. By beginning of March 2025, the 50th anniversary of the women’s day was also celebrated. Some countries (Algeria, China, Malaysia, Thailand, …) issued stamps at this occasion and others will probably do, but there is no joint character with all these stamps.

We are still missing information about Qatar stamps that could have been issued since January 31, 2025 in association with the (announced as joint issue) stamp from Argentina. Any help is welcome.

The Volume XVI of the catalogue has been updated accordingly.
