Issued in 1969 by the Principality of Liechtenstein, this 50-rappen stamp commemorates the 10th anniversary of CEPT (European Conference of Postal and Telecommunications Administrations), established in 1959. The design features the word "EUROPA" stylized in a bold, architectural motif that emphasizes unity and collaboration. The vibrant red and green color scheme symbolizes progress and cohesion within Europe. A classic example of mid-century European philatelic design, this stamp holds strong thematic value for Europa collectors.
