1955 International Civil Aviation Organization


The International Civil Aviation Organization (ICAO) is a specialized agency of the United Nation
whose mandate is to ensure the safe, efficient and orderly evolution of international civil aviation.
ICAO has its headquarters in Montreal. Created in 1944 and operational in 1945, it has grown to an organization with over 180 Contracting States. ICAO's aim is the safe and orderly development of all aspects of international civil aeronautics. It provides the forum whereby requirements and procedures in need of standardization may be introduced, studied and resolved.
On June 1, 1955, the Canadian Post Office issued a 5 cents stamp designed by Walter Lohse to commemorate ICAO's tenth anniversary.

A web site dedicated to the postal history of the IACO can be found here.
