This colorful semi-postal stamp from Germany (Bundespost) was issued in 1990 to commemorate the 10th International Youth Stamp Exhibition in Düsseldorf. The playful design features stylized children from different cultures, symbolizing global friendship and the spirit of youth philately. The stamp carries a denomination of 100 + 50 pfennig, where the surcharge supported youth philatelic activities. Its modern graphic style and international theme make it an appealing collectible for topical collectors of youth, exhibitions, and philately themes.
