Issued by Germany – Berlin (Deutsche Bundespost Berlin) as part of the 1968 “Für die Jugend” charity series, this attractive semi-postal stamp features the European wildcat (Wildkatze) illustrated in a bold, modern wildlife style. The additional +5 pfennig surcharge supported youth welfare programs, making it both a postal and philanthropic issue. The strong red background and detailed feline artwork give the stamp striking album presence. A popular thematic choice for animal, wildlife, and conservation collectors. Clean examples with sharp perforations and bright colour are especially desirable. A classic late-1960s Berlin semi-postal with steady collector demand.
