STAMP ISSUES RELATED TO ICAO (1945-1977)

 

Cameroon : 20th Anniversary of ICAO

 

Issue date: 15/03/1967

 

 

Aircraft and ICAO emblem.

This stamp shows two errors:  

  1. "de l'" is missing in the French name of the Organization, which should be written Organisation de l’aviation civile internationale. Moreover, only the first word of the name should be capitalized.
  2. The ICAO logo must include four concentric circles. The design on this stamp displays only three circles.

     

Background: ICAO provided instructions to the Contracting States to commemorate its 20th anniversary on 7 December 1964, corresponding to the anniversary of the signing of the Convention on International Civil Aviation, in Chicago. This country still calculated the 20th anniversary on the basis of the constitution of the new permanent International Civil Aviation Organization (ICAO) on 4 April 1947; this is considered as an error.
