This commemorative stamp from Portugal was issued in 1982 to celebrate the 25th Anniversary of the European Economic Community (CEE), the organization that later evolved into the European Union. The modern graphic design features a dynamic arrangement of circular emblems displaying the flags of member nations, connected by flowing bands symbolizing unity and cooperation across Europe. Designed by Acácio Santos, the stamp reflects the spirit of economic partnership and integration among European countries during the late 20th century. Its bold geometric style and vibrant colors make it a striking piece for collectors of European integration, political history, and modern graphic stamp design.
