This original postcard is from the 1933 Century Of Progress (Chicago World's Fair) which was held in Chicago. It is in very good condition but is yellowed and the front features the "Firestone Factory & Exhibition Building with Firestone Singing Color Fountain in Foreground, A Century Of Progress". The reverse side features a postcard format, which is unused and a paragraph that says "Firestone Factory & Exhibition Building at A Century of Progress, Chicago, contains a complete production line of the most modern & efficient tire making machinery in the world" and measures approx. 5 1/2" x 3 1/2".
