September 30, 1933 – Iowa Day at the Chicago World’s Fair.
This special postal cover (above) is postmarked on Iowa Day at the Fair. This tradition of having a special day set aside for a specific state began with the St. Louis World’s Fair in 1904.
In 1933, during the Great Depression, Chicago held the Century of Progress Exposition to celebrate the 100th anniversary of its incorporation as a village. The fair was held on the lake-front & featured outstanding exhibits on the latest advancements in science and technology. It brought an enormous amount of business to the city and was a huge relief from the woes of the Great Depression.
