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 has slightly worn corners and the front features the "Illinois Host House". The reverse side features a postcard format, which is unused and a paragraph that says "Headquarters for the citizens of Illinois and Official guests of the state. It is located next to the Sears Roebuck Building, just south of the northwest entrance to the Fair" and measures approx. 5 1/2" x 3 1/2".
