Yugoslavia 75th Anniversary of the UPU on First Day Cover, Zagreb 1950

Yugoslavia · 1950 · 5 Dinar & 10 Dinar

This first day cover features two stamps issued by Yugoslavia to commemorate the 75th anniversary of the Universal Postal Union (UPU). The 5 Dinar stamp depicts a mail plane flying over a globe, while the 10 Dinar stamp shows a post horn and a map of the world. The cover is cancelled in Zagreb on the first day of issue, October 9, 1950, with a special cancel from the Philatelic Society of Zagreb.

Issued in 1950, these stamps celebrate the international cooperation fostered by the UPU, a specialized agency of the United Nations that coordinates postal policies among member nations. The cover originates from Zagreb, the capital of the People's Republic of Croatia, which was a constituent republic of the Federal People's Republic of Yugoslavia at the time.
