On February 28, 2023, the joint issue between Armenia and Slovakia was released as scheduled. It celebrates the 30th anniversary of relationship and the stamps depict the Tatev Monastery, in Syunik region (Armenia) built during the ninth century, included now in the UNESCO World Cultural Heritage list and the St George’s Church, in Nitrianska Blatnica (Slovakia) also from the ninth century. The particularityy of this issue comes from the way the stamps are produced. The stamps are printed in a pane size [5×9] containing both stamps, type A in the top half, type B in the bottom half, together with 5 central labels forming a central cross. The overall structure looks the following: 3 rows of 5 stamps A, a row containing 2 pairs of stamp A separated by a label, then a row with one stamp A, three labels and one stamp B, and a row containing 2 pairs of stamp B separated by a label, and at the bottom 3 rows of 5 stamps B. This structure leads to a sheet containing 20 stamps A, 20 stamps B and 5 labels. Each sheet can contain vertical pairs of se-tenant A-B stamps, but limited to two units per pane. Knowing that the total printing of stamps is 2×20,000 for Armenia and 2×100,000 for Slovakia, only respectively 1,000 and 5,000 panes have been printed containing a maximum of 2,000 and 10,000 vertical pairs respectively.
These miniature sheets could be cut a different way, by keeping in one piece the five central labels with the 2 stamps A and 2 stamps B in the four corners. Only a maximum of 1,000 units for Armenia and 5,000 for Slovakia of these cut outs of printed panels can theoretically exist. The central labels represent the flags of both countries, and the coat of arms of Armenia, respectively Slovakia. The two other labels contain the words ‘Armenia – Slovakia joint issue’ in English and Armenian for Armenia, in Slovak and Armenian for Slovakia.






Jaap Sarelse (The Netherlands) provided some information about the potential Cambodia-South Korea joint issue that was supposed to be released on February 10, 2023. The original source was the South Korean Philatelic Service. However, Jaap learned from two Cambodian sellers that no such an issue is mentioned in the 2023 list of Cambodian stamps. Also a seller from South Korea confirmed this is not a joint issue. The top margin of the souvenir sheet printed by South Korea is entitled “Protecting Endangered Species in Korea – Cambodia REDD+ Joint Project Area”, meaning the ‘joint’ character is refering to an area between both countries, and a common project, but not to this stamp issue. This entry is removed from the catalogue.
Don Birschel (USA) reports also about stamps released at the occasion of the Kuwait 62nd national day by both Kuwait (February 22, 2023) and the United Arab Emirates (February 25, 2023). Even if the Kuwait 62nd national day is celebrated by the UAE, there are no hints of collaboration between both countries and stamps are different. These cannot be considered as a joint issue.


A surprising joint issue between India and Luxembourg will be released on March 14, 2023. The information was first provided by Souvik Ghatak (India) and Kenneth Sequeira (Singapore). The Luxembourg post made the announcement as early as March 2, 2023, but it took some time for India to confirm, despite the fact that the designer of the miniature sheet is of Indian origin. The stamps relate to the 75th anniversary of the relationship between both countries and is illustrated by sculptures by Amar Nath Sehgal (1922-2007), an Indian sculptor, painter and poet who spent a large part of his life in the Grand Duchy of Luxembourg.
