Issued by Yugoslavia in 1985, this 70-denomination commemorative stamp celebrates the TID ’85 Forum, an event associated with international sporting cooperation along the Danube region. The modern graphic design features a stylized athlete and water motif, symbolizing endurance sports such as swimming and water competitions. Designed by O. Čudov, the stamp reflects the bold geometric style common in 1980s Yugoslav philatelic art. The laurel wreath with “30” signifies a milestone or anniversary linked to the event. This issue is an appealing collectible for sports-themed, Olympic-style, and Yugoslavian stamp collections.
