This is a view of aircraft hangers under construction on the Yerba Buena Shoals Fill - now known as Treasure Island. The buildings were to be used as exhibit halls during the 1939 Golden Gate International Exposition. Some of the buildings were to be used as part of an airport facility after the Exposition. World War II caused a change of plans and the U.S. Navy took control of the island where it remained for the next half-century.
