Both previous blog pages triggered attention from collectors and resulted in additional information that help complete the catalogue:

Regarding the Arab Postal Day issue [T20250803], two additional countries have to be added to the already reported list (Algeria, Iraq, Tunisia, and the United Arab Emirates) namely, Egypt and Oman which issued their stamps respectively on August 3, 2025 and August 10, 2025 (Information provided by Mohamed Achour Ali Ahmed, Algeria and Ali Allawati, Oman).

The 80th Arab League anniversary issue from March 22, 2025 [T20250322] was also completed by two stamps issued in miniature sheets of 3 pairs from the United Arab Emirates. These stamps were issued on August 18, 2025 (Information provided by Kenneth Sequeira, Singapore).

The previous blog page was also missing the image of the Russian stamp jointly issued with North Korea on August 15, 2025. Illustration was provided by Kenneth Sequeira, Singapore, confirming the twin character.

I also made a comment earlier that embroided stamps are never used postally. Henri Aronis (France) provided a proof that this can happen with a Swiss stamp (year 2000), although not part of a joint issue. As expected, the thickness of the ‘stamp’ makes cancellation illegible. This cover was sent from Switzerland to Niger. Thanks Henri.

Jaap Sarelse (the Netherlands) reacted on the comments provided earlier about the July 5, 2025 Cape Verde – Portugal joint issue and at the same time provided information about Angola, a third country joining this issue, with the following:

“The text suggests that it is a joint issue in which only Cape Verde and Portugal are involved. However, Angola is also involved with an identical stamp. Not to commemorate Angolan independence, but purely focused on the independence of Cape Verde. Some evidence:

• In the leaflet of the Portuguese Post (6 pages) the text on page 5, 7^th and 8^th line from the bottom reads: ‘To help consolidate the historic memory of the founding of the Republic of Cabo Verde, a joint stamp issue is being released by Angola, Cabo Verde and Portugal’.
• On page 5, one can find the stamps of Angola on the top row. Cabo Verde is also mentioned on this stamp at the bottom right.
• Finally, only Cabo Verde is mentioned in the logo on page 1. I suspect that in the context of ’50 anos Independência Nacional’ Angola will get its own joint issue and that the name Angola will then adorn below the stars in the logo“

Thanks, Jaap for this complement. Catalogue will be updated. Here are the additional illustrations (Angola stamp illustrations provided by Kenneth Sequeira):

Additional information relative to issues to come include the following:

• The Oman – Russia originally scheduled for April 22, 2025, is now postponed to September 26, 2025 (Oman source) or October 15, 2025 (Russian source), not clear at this stage. It will show maps and honour Omani explorer Ahmed bin Majid and the Russian traveler Afanasy Nikitin
• Kenneth Sequeira reported also two modifications in the Russian philatelic programme for 2025: a) the RCC stamps will be issued on August 23, 2025, but over the past years these stamps involving all CIS countries were not anymore considered as joint and there is no hint that this will change this year; b) the anniversary of the liberation of Korea will be celebrated by overprinting the August 15, 2025 joint issue with North Korea. These stamps will be issued on September 2, 2025
• On October 7, 2025, the France – Japan is also confirmed. Japan stamp designs became available (information provided by Dominique Josse, France)

• On August 15, 2025, Argentina issued a stamp to celebrate 60 years of immigration from Korea. No stamps related to the same topic was seen so far in the South Korea philatelic program. This issue may remain unilateral (information provided by Enzo Cafaro, Italy)

• Our friend Luis Alejandro Malanco Reyes (Mexico) is working on a Mexican stamp catalogue (which of course includes also joint issues involving Mexico) and brought on line the first part of his work (years 2001-2025) with free access: Catálogo Filatélico México . Congratulations Luis and keep doing the good job.

Finally, some information about the next joint crypto-stamps issue (not recommanded to include in the joint issue collection as explained earlier): This will be the fourth crypto joint issue after the 2022 Austria-Netherlands (Ox), 2023 Austria-Luxembourg-Netherlands (Lion) and 2024 Austria-Belgium-Luxembourg-Netherlands (dragon) issues. The theme for this fourth issue is the Greek world of the gods. Five countries will participate and they made the following choice: Portugal – Poseidon, Austria – Zeus and Hera (2 stamps), Belgium – Athena, Luxembourg – Artemis and the Netherlands – Hermes.

Jaap Sarelse has succesfully created joint stamp covers with the previous crypto stamps and will try again this year with the six stamps. He provided the picture of the copy from year 2024. Such documents are close to unique.

The catalogue was update with all above new data. See updated Vol 1, Vol 15 and Vol 16
