Established in 1874, the Universal Postal Union (UPU) includes most postal administrations. Canada became a member in 1878 and hosted the UPU Executive Committee Meeting in Ottawa in 1933. In 1957, the 14th UPU Congress was held in Ottawa, with its proceedings occurring in the House of Commons. CAPEX 78 International Philatelic Exhibition, held from 9 to 18 June 1978 in the Automotive Building, Exhibition Place, Toronto, was the occasion to commemorate the centenary of Canada joining the Union. The acronym CAPEX stands for CAnadian Philatelic EXhibition.


Show imprint

developed by the UNPA

Sponsored by the Royal Philatelic Society of Canada, under the patronage of the Fédération Internationale de Philatélie (FIP) and under the auspices of the Federación Interamericana de Filatelia (FIAF), the CAPEX-78 show was at that date the largest and most important in Canadian postal history. This was the nation's second international stamp exhibition, the first having been held in 1951.


As participant in the exhibition, the United Nations Postal Administration (UNPA) in cooperation with ICAO designed the special blue show imprint for this exhibition; the flight paths of the UN Geneva stamps (Scott #77-78) are reproduced on this hand-stamp.


Several philatelic items released in relation with the United Nations issue ICAO Safety in the Air (12 June 1978) were stamped with the special show imprint as noted hereafter. Some countries represented at the exhibition had their own cancels.
