This commemorative stamp from Portugal was issued in 1982 to celebrate the 25th Anniversary of the CEE (Comunidade Económica Europeia / European Economic Community). The modern graphic design features a dynamic arrangement of circular symbols displaying the flags of several European nations, connected by flowing colored bands representing unity and cooperation. Designed by Acácio Santos, the stamp reflects the spirit of European integration during the late 20th century. Printed by INCM (Imprensa Nacional-Casa da Moeda), it carries the denomination 27$00 escudos. The vibrant geometric style and strong historical theme make it an attractive piece for collectors of Europa, European integration, and political history philately.
