Issued by East Germany (DDR) in 1985, this se-tenant pair with label commemorates the XII World Festival of Youth and Students held in Moscow. The 20+5 Pfennig stamp depicts young people studying together under a rainbow banner, symbolizing international solidarity, while the 50 Pfennig stamp shows cheering youth with St. Basil’s Cathedral in the background, representing unity and enthusiasm. The central label carries the official festival emblem and the inscription "Für antiimperialistische Solidarität – Frieden und Freundschaft" (“For anti-imperialist solidarity – peace and friendship”). A powerful design reflecting Cold War-era socialist ideals of global youth cooperation.
