Issued by the United Kingdom in 1969, this 9d commemorative stamp marks the 10th anniversary of CEPT (Conference of European Postal and Telecommunications Administrations). The bold geometric design features the word EUROPA projecting forward, symbolizing European unity and progress, with the years 1959–1969 on either side. The profile of Queen Elizabeth II appears at the upper right, alongside the CEPT emblem. A striking and modern design, it is a key issue in the Europa/CEPT thematic series highly valued by collectors of European integration stamps.
