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.
