Issued by Austria in 1959, this stamp commemorates the 5th anniversary of the Europa CEPT postal cooperation among European countries. The design features a stylized flower radiating petals, symbolizing unity and growth across Europe. At the center appears the CEPT emblem, representing the European Conference of Postal and Telecommunications Administrations. Printed in a deep blue tone, the stamp reflects the early classic Europa issue design shared across participating countries, making it a desirable thematic piece for collectors of Europa, European unity, and postal history.
