A 'members only' souvenir cover produced by the Antarctica Services.
ANTARCTICA SERVICES and the associated ANTARCTIC PROTECTION SOCIETY were founded by Klaus Arne Pedersen at the World Expo in Brisbane, Australia, on August 8, 1988. The goal was to provide an easy way for the members of the APS to receive optimal covers whose individual handling would be both very difficult and costly.
