The 1933 Chicago World's Fair, A Century of Progress, opened 90 years ago. This is a first day postcard, rather than a cover. There were lots of picture postcards issued commemorating the two year fair. I have around 80 of them from at least eight sets. Lord knows how many sets there were.
This card appropriately has the one cent Fort Dearborn stamp. Also issued on May 25, 1933 was a violet three cent letter rate stamp depicting the modern Federal Building.
