English: View of the main building, boarding gate area, and airport apron of Cleveland Municipal Airport in 1936 (see written note on photo frame). Several airliners are visible. The three closest ones are Boeing 247s, probably all of United Air Lines (the leftmost one, registered NC13355, is definitely with United). The 247 in the right rear, with its nose baggage compartment open, is an original model with Townend ring engine cowlings; the other two are the improved 247D version, with NACA engine cowlings and rubber pneumatic deicing boots on the leading edges of the wings and tail. In the further distance can be seen two airliners of American Airlines: a Stinson Model A trimotor behind the leftmost Boeing, and a Curtiss T-32 Condor II biplane partly visible behind the building roof.
