This elegant 1968 Europa issue from France features the symbolic CEPT key, representing the unity and strength of European nations through communication and progress. The design shows a stylized key head with the letters “C.E.P.T.” arranged in a circular formation, embodying cooperation under the European Conference of Postal and Telecommunications Administrations. The two stamps differ in color and denomination—magenta and ochre for 0.30 franc, brown and red for 0.60 franc—both beautifully engraved in classical French precision. These are part of the common “Key of Europe” design adopted by multiple European postal administrations that year.
