Issued by the United Kingdom in 1969, this bold 9d commemorative marks the 10th anniversary of CEPT (European Conference of Postal and Telecommunications Administrations). The design features dynamic, geometric lettering transitioning from “EUROPA” to “CEPT,” symbolizing European postal cooperation from 1959 to 1969. The colours shift from deep blue to green, reflecting progress and unity across the continent. At right appears the classic effigy of Queen Elizabeth II alongside the CEPT emblem. A striking and modernist Europa thematic piece, sought after by both Europa and British commemorative collectors.
