Issued in 1965, this Austrian stamp commemorates the 5th Anniversary of the European Conference of Postal and Telecommunications Administrations (CEPT). The design, printed in deep blue, features a stylized flower with 19 petals, symbolizing the unity and cooperation of European nations. At the center of the bloom appears the CEPT logo — the interlocking letters C, E, P, and T — representing communication and solidarity across Europe. The inscription “Vᵉ Anniversaire” marks the milestone year, and “EUROPA” below emphasizes the pan-European scope of the issue.

This elegant and minimalist design reflects mid-1960s European optimism toward integration and cooperation through postal symbolism. It was part of a coordinated Europa series issued by multiple CEPT member states in 1965.
