While the month of April 2024 remained relatively quiet in terms of new joint issues (Israel-Romania on April 17 and Italy San marino on April 20), the month of May saw some interesting releases which are now listed below.

May 9, 2024: This is the official date of this year’s PostEurop issue. The topic is related to ‘Underwater fauna and flora’. A large number of countries issued their stamp(s) on the anniversary date of May 9, but as the design and dates of issue are remaining within the hands of each postal administration, similarly to previous years, the 2024 issue is not considered as joint, on the contrary to last year. This series is just reported in the catalogue for information for collectors of Europa / Europa CEPT / PostEurop stamps. So far, 57 countries have already released their stamp(s) or have announced their participation. Information is missing only for Albania, Armenia, Kazakhstan and Ukraine [N20240509].

May 21, 2024: Morocco and Romania celebrate cultural relations between both countries through a pair of identical stamps related to folk art. This is a twin issue [T1] representing traditional costumes and ceramic or porcelain objects from the regions of Vâlcea and Horezu (Romania), or from Fez (Morocco) [T20240521].

May 21, 2024: The 150^th anniversary of the birthday of Guglielmo Marconi (1874-1937) is celebrated by the Vatican State and the Sovereign Military Order of Malta (SMOM) through a twin issue representing the Italian inventor in front of dedicated equipment. Unfortunately, as the UPU does not recognize SMOM a an official postal administration, this issue remains described in the catalogue, but under the heading non-approved/twin issue [N/T1] [N20240521]. Each individual collector to decide if he/she wants to keep this issue in his/her collection.

May 26, 2024: The accession of Frederic X to the Danish throne is celebrated through joint souvenir sheets issued by Denmark, Faroe Islands and Greenland. Due to the direct link between these three postal administrations, this joint issue is considered as a Territorial twin issue [TD] and will be referenced as [D20240526]. The identical souvenir sheets with one stamp showing the portrait of King Frederic X were issued at the date of the anniversary of the King (born on May 26, 1968). King Frederic X is officially reigning since January 14, 2024.

May 31, 2024: as a last minute issue, we were informed that China PR and Malaysia have issued a joint pair of stamps at the occasion of the 50th anniversary of the diplomatic relationship between both countries (Source: Adam Paish, UK). The stamps represent two local large trees (Pine and Merbau/malaka teak) from both countries.

The potential Mongolia – Switzerland joint issue expected at the occasion of the 60th anniversary of the diplomatic relationship between both countries resulted in a souvenir sheet issued unilaterally by Mongolia on May 20, 2024 (see https://montsame.mn/en/read/344262), so, not a joint issue.

The Tunisia – Russia joint issue initially scheduled for May 24, 2024 (Art – Painter Roubtzoff) is now postponed to September 9, 2024 (Russian philatelic program).

We are still missing information about the Indian stamps linked to the already announced Israel Purim souvenir sheet that was supposed to be released on May 7, 2024.

The catalogue Part 1 and Part 15 have been updated accordingly.
