Miscellaneous Philatelic Exhibitions


In addition to the well-defined exhibitions directly related to ICAO, such as the International Exhibition of Air Mail Postage (1969) or the Philatelic Exhibition on Aviation (1994), the ICAO postal history contains many items related to various philatelic or non-philatelic exhibitions held worldwide. The following pictures display the major ones.

The T-34 remained in service more than six decades after it was first designed.
