Opening Of CIPEX
America hosted its first international stamp exhibition in 1913. This was followed by another in 1926, for which the famed White Plains souvenir sheet, U.S. #630, was issued. After this, the shows exhibitions were to be held every 10 years, with the next one coming in 1936. However, for the 1940s, the U.S. decided to delay the exhibition for a year so it could coincide with the 100th anniversary of America’s first stamps. For this reason, it became known as CIPEX – the Centenary International Philatelic Exhibition.
A notable and unfortunate event that preceded the exhibition was the sudden death of noted collector and CIPEX chairman Alfred F. Lichtenstein. In response, the organizing committee created a Court of Honor in his name. More than 200 collectors from the U.S. and around the world lent some of their most prized stamps for this display – creating a Court of Honor like none ever seen before. It included virtually every variety of stamp issued between 1840 and 1870.
