The Chicago Theater is located on north State St. in Chicago. It was built in 1921 at a cost of four million dollars (fifty-six million today). It has 3,880 seats and was the first movie palace, a prototype for all the ones to follow. It was also one of the first to use air conditioning. The first photo is dated 1921. The third photo showing the interior is credited to Dave DiCello. (Click to enlarge.)
