In page 1939 New York World's Fair:

"

The fair was open for two seasons, from April to October each year, and was officially closed permanently on October 27, 1940.[1] To get the fair's budget overruns under control before the 1940 season and to augment gate revenues, Whalen was replaced by banker Harvey Gibson. In addition, much greater emphasis was placed on the amusement features and less on the educational and uplifting exhibits. The great fair attracted over 45 million visitors and generated roughly $48 million in revenue. Since the Fair Corporation had invested 67 million dollars (in addition to nearly a hundred million dollars from other sources), it was a financial failure, and the corporation declared bankruptcy.
