The displays are shown in glass frames, and the exhibition is normally accompanied by stamp dealer bourses and post office stands where stamps and other philatelic items may be purchased.
[1] Exhibitions are normally of international, national, regional or local scope.
The most prestigious international exhibitions are those for which Fédération Internationale de Philatélie (FIP) patronage is granted, although the increasing cost of complying with FIP requirements has caused concern with some exhibition organisers, particularly in the developing world.
Philatelic judging is done according to agreed criteria,[4] and in the case of international exhibitions the rules of the FIP are normally used.
It is common for commemorative covers and souvenir sheets to be produced for the larger exhibitions and these are a recognised collecting specialism in themselves.
