Issued by the Federal Republic of Germany in 1960, this 20 Pfennig green stamp commemorates UNESCO’s mission to foster international collaboration through education, science, and culture. The design features six stylized hands forming a protective circle around the UNESCO emblem, symbolizing unity and cooperation among nations. The minimalist grid background represents the structured, interconnected efforts of global peacebuilding. This issue reflects postwar Germany’s commitment to international reconstruction and cultural dialogue under the auspices of the United Nations.
