November: discoveries and complements

Madagascar finally joined the countries celebrating the 150th anniversary of the UPU from October 9, 2024 [T20241009] with the same common stamp. This country issued its stamp on December 30, 2024 (actually printed by the Tunisian Post Printing Office, on November 4, 2024) and produced stamps in panes of 20 [4×5] and a souvenir sheet containing a block of 4 stamps [2×2] (Source: Benjamin Busch)

The stamps from Iran so far reported in the catalogue in this same UPU anniversary series are described as customized personalized stamps, not officially recognized and hence, not part of the series. On July 7, 2025, Iran issued an official stamp that was only reported recently. Iran integrates officially this UPU series listed under [T20241009]. The new (horizontal shape) stamp is shown below next to the first customized (vertical shape) stamps.

On September 5, 2022, several countries dedicated at least one stamp to the International Forum on Tiger Population Preservation in Vladivostok, Russia. This Issue reported under [P20220905] involved all countries that are the tiger’s habitat, including Cambodia (September 22) – India (September 1) – Korea (North) – Laos (September 1) – Malaysia – Myanmar – Russia – Vietnam. Among them, Myanmar issued three stamps in panes. This country re-issued recently (2025, exact date unknown) these stamps in a leaflet/souvenir sheet as a triplet of se-tenant stamps. Illustrations of the original stamps and the new reprint are provided below (Source: David Caleb, Enzo Cafaro).

Libya is a new country to be added to the Post day issue “Towards more innovative postal services” from August 3, 2025, which included already Algeria – Egypt – Iraq – Oman – Tunisia (August 4) and the United Arab Emirates (Kenneth Sequeira, Dubai).

An older series of stamps dedicated to the Covid pandemy was discovered recently (Costas Mengoulis). These stamps produced by Stamperija on behalf of Chad, Guinea-Bissau, Liberia, Niger and Sao Tome and Principe have not been reported so far, and their exact date of issue remains unknown. Each country proposes a pane with 16 different stamps, identical from one country to another. Knowing the source and the reason of this issue (mainly to fool collectors), we do not recommend to buy and to include them in your collection. However they need to be reported in the catalogue, but without details, with the same purchase recommendations. In absence of details, these stamps have been added to the description of [B20200427].

The catalogue pages have been updated accordingly. Thanks to all the contributors mentionned between brackets in the text.

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.

June 2025 news

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.

AICEP, UPU and dolls

Upon a proposal from Portugal, the five lusophone countries Angola, Brazil, Cape Verde, Macau and Portugal came together to celebrate with a twin issue the 35th anniversary of AICEP (Associação Internacional das Communicaçóes de Expressão Portuguesa – International Association of Portuguese Expression Communications). Stamps with the same design were all released on May 13, 2025, during the XXXII AICEP forum.

This AICEP anniversary issue could include the other countries members of the association, namely Guinea Bissau, Mozambique, Sao Tome and Principe and Timor, but so far no information is available from these countries (images provided by Enzo Cafaro, Italy and Kenneth Sequeira, SingaporeImage from Angola is still missing, although participation is confirmed).

In the previous blog page, we described souvenir sheets released on April 25, 2025 by Belarus and Russia to commemorate the 80th anniversary of the victory of the Soviet people in the Great Patriotic War (1941-1945). Kenneth Sequeira, Singapore, reported stamps issued by Kazakhstan and Mongolia at the same occasion. The Kazakhstan souvenir sheet including a round stamp was issued also at the same date of April 25, 2025 and must be added to the previous countries. This souvenir sheet, printed only at 2,500 samples, became also available with a “PCC/RSS” overprint (Regional Commonwealth in the Field of Communication) within the stamp, not related to this joint issue. Mongolia produced a completely different stamp in sheetlets of 4 [2×2] released on April 30, 2025. It is not clear if this fourth country participated to a joint effort with the three other countries, and for the time being these stamps will only be described as a footnote in the same entry.

Enzo Cafaro, Italy, was able to provide the preliminary sketches of the joint issue between the Russian Federation and the Dominican Republic planned for July 17, 2025. The final design may still change slightly but illustrations show that it will be almost identical for both countries.

Some surprising self-named joint issues appeared over the past months. The first one is related to the 90th anniversary of the relationship between Egypt and Switzerland. Egypt issued a stamp, but nothing was produced on the Swiss side. This Egyptian stamp will definitely remain an unilateral issue.

Also, Cambodia and Cyprus revealed by mid May (19 or 20) a so-called joint issue commemorating the 25th anniversary of their relationship. This information appeared on a UPU Facebook blog page (confirming a kind of postal commemoration), but the design that is shown looks like a stamp only through the perforations: there is no identified single country mentionned on the stamp, nor a denomination. As additional information from both countries is missing, it may be possible that this picture is just the symbolic design of the anniversary framed with perforations, and not a stamp, or at least not the final design. More information is needed here.

Ali Allawati, Oman, provided information from his country: next to the recently issued joint issue between Oman and Singapore reported under T20250221, Ali describes first an Iran-Oman issue (see illustration below), announced on May 27, 2025, issued in honour of the official Visit of His Excellency Dr. Masoud Pezeshkian, President of the Islamic Republic of Iran, to the Sultanate of Oman. The Oman stamp is not yet available for purchase, and information is missing from the Iranian side.

On April 22, 2025, Oman Post had also annnounced the issuance of a joint stamp celebrating the enduring relations between the Russian Federation and Oman, coinciding with the state visit of His Majesty Sultan Haitham bin Tarik to Russia. At this stage this is the only information available.

To the already very large October 9, 2024 UPU joint issue, one has also to add Aruba as a new country, which released a souvenir sheet containing a triangular shaped stamp, showing the UPU 150th anniversary logo in the margin. The souvenir sheet was issued on October 9, 2024, but was discovered only recently.

For those interested in the 2025 Europa stamps, this is the status of the issuing programme. The stamps with common topic National archeological discoveries (which topic was postponed to 2025 from originally 2024), were issued with a date centered around May 9, 2025. This year, these stamps are not considered as joint and will be reported under a simple list entitled [N20250509]. In the following list, empty bracket represent countries that announced their participation but from which data and in particular issue date are still missing, while absence of date means that those stamps were issued on May 9, 2025: Aland – Albania () – Andorra (French) (May 11) – Andorra (Spanish) – Armenia (April 29) – Artsakh (Armenia) () – Austria (May 1) – Azerbaijan (May 5) – Azores – Belgium (April 7) – Bosnia Herzegovina – Bosnia Herzegovina (Croatia) (April 5) – Bosnia Herzegovina (Serbia) (April 24) – Bulgaria – Croatia – Cyprus – Cyprus (Turkish) (May 8) – Czech Republic (May 7) – Denmark (May 28) – Estonia – Faroe (May 26) – Finland (May 7) – France – Georgia – Germany (May 8) – Gibraltar (May 8) – Greece (May 7) – Greenland (May 26) – Guernsey (May 1) – Hungary – Ireland (May 8) – Isle of Man (April 8) – Italy – Jersey (May 5) – Kazakhstan () – Latvia – Liechtenstein (April 1) – Lithuania (April 25) – Luxembourg (May 6) – Macedonia (North) (May 7) – Madeira – Malta – Moldova (April 11) – Monaco – Montenegro – Netherlands – Norway (April 24) – Poland (April 28) – Portugal – Romania (April 29) – San Marino (February 11) – Serbia (May 6) – Slovakia (April 30) – Slovenia – Spain – Sweden (April 24) – Switzerland (May 8) – Türkiye (Turkey) – Ukraine (August) – Vatican (May 27)

Eventually, we learned also that a new crypto-stamp joint issue involving Austria, Belgium, Luxembourg, the Netherlands and Portugal. Details will be known during the summer.

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: second update

Since the publication of the original blog page related to the description of stamps linked to the 150th UPU anniversary (October 9, 2024) and the first update, as expected, additional stamps and countries have been discovered and are now described below. It seems this is still not the last update. This complementary list is divided on the basis of the same structure as the one provided earlier, in the first update:

  1. Countries of Type A (Twin [T1], same date, same design), additional country: El Salvador (October 9, 2024).

2. New country of Type B (Concerted [C1], different dates, same design): Nepal (December 17).

The Dominican Republic stamp was issued October 26, 2024 and therefore has to be moved in this sub-category. Same for Lybia which stamps were issued on October 22, 2024 instead of October 9, 2024. In Iran, two stamps appeared also, printed in miniature sheets of 4 stamps but in fact made of an illustrated label with the UPU anniversary logos, attached to a stamp with text only. It seems that these stamps correspond to (privately) personalized stamps with limited printing runs (additional information is needed here). As belonging to this sub-group, these two stamps will be described in the catalogue in italics characters.

3. New countries of Type C (modified design – only logo [T2], [C2]): Ghana (), Italy (November 21), the Philippines ().

The exact date of issue for the Uzbekistan stamp is known now to be May 17, 2024. The United Nations stamps (Geneva, New York, and Vienna) had to be re-integrated in this category as the miniature sheets of 9 stamps [3×3] bear in the top margin the logo of the 150 UPU anniversary. These stamps were issued already on May 30, 2024.

Special miniature sheets including eight different countries have been produced and should be considered as se-tenant issues [S]. These stamps were printed with two different denominations, as perforated and non-perforated miniature sheets, at very low printing runs (100 units for each of the two perforated miniature sheets and 30 for the non-perforated ones). The countries involved in these items include Burundi, Central Africa, Djibouti, Guinea, Guinea-Bissau, Liberia, Sierra Leone and Togo (with stamp type B for this country). Due to the small printings runs, these miniature sheets must be considered as material to abuse collectors. They will be listed in the catalogue but in italics, just for information purpose. The printer of these countries also decided to create two postal cards per country with the same indicia (postal stationery) as pane stamps and souvenir sheet stamps, sold at very high prices, which must also be considered with the same status (abusive).

4. New country of Type D (different design, but same date [P1]): Honduras (October 9, 2024), 2 stamps

5. New country of Type E (different design, different date [N]): no new stamps

The UPU anniversary related stamp from the Netherlands is not an official Dutch post issue, but a personalized stamp, meaning it has to be filed as of private origin, in limited edition (information provided by Cesar Ittman, the Netherlands). The situation is similar for the Liechtenstein stamp, the second French stamp, Iran stamps, which are all to be considered as personalized or customized and/or private issues (all to be reported with italics characters in the catalogue).

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).

Iran – China 2021

Kazem Alamdari (Iran) was able to provide information about and pictures of the Iranian stamps issued on December 11, 2021 jointly with China PR [T20211211]. The Iranian stamps were issued as se-tenant pairs with a printing run of 60,000 pairs.

This modification led to the change of version of Vol 14 (to V3.02). At the same time Vol 15 was also updated with the description of the first joint issue of the year (China – Macau Tiger year issue).
