Stamp World London 1990

Stamp World London 90 was an international stamp exhibition held 3-13 May 1990 at the Alexandra Palace, London.

The exhibition celebrated the 150th anniversary of the introduction of adhesive postage stamps, the first two being the Uniform Penny Post and the Penny Black. The centennial of this event occurred in 1940, and any celebration was overshadowed by the reality of World War II. Commemorative stamps were issued by several countries coinciding with this exhibition.
