Issued by the République Française in 1969, this 0.40 franc stamp commemorates the 10th anniversary of the European Conference of Postal and Telecommunications Administrations (CEPT), founded in 1959 to promote European cooperation. The striking design features the word EUROPA stylized as a three-dimensional building, symbolizing the strong and unified structure of Europe built on collaboration and communication. The bold red tone emphasizes energy, unity, and progress during a time of continental reconstruction and optimism.
