1938. The cover, no longer set off by a silver border, depicts the Trylon (triangular-shaped pylon) and Perisphere (18-story sphere) that were symbols of the New York World's Fair of 1939. The fair's theme was "The World of tomorrow". Against a bluish-green background a purplish-red sphere encloses a car floating above a man in a welding mask holding a welding gun giving off hot sparks. On the right of the picture white columns trimmed in peach and copper tones, with lower rounded arches, support a throughway sloping from the sky, through the Trylon, and towards the welding. Along the surface of the roadway are people holding banners and several sleek vehicles, one a tram or train, all headed into the future.
