The following Associated Press typewritten notation attached to the back of the photo reads "PREVIEW OF BAY AIRPORT San Francisco, August 15--This combination photo and drawing gives a preview of the big San Francisco Airport to be opened in 1940. It will occupy a man-made island [later known as Treasure Island] now being dreged upin San Francisco Bay. The three permanent buildings shown--costing $1,600,000--will form part of the Golden Gate International Expostion to be held on the site in 1939." The view is taken from a slight elevation, looking toward the Oakland-Berkeley Hills. The three structures, from left center to right center are a semiciruclar three-story expostion building, and two large aircraft hangars. [All three are standing and in use as of this date. February 15, 2001 JM] The semi-circular building houses offices and a museum. Airplanes are parked near the edge of the field at right lower, and a four-engine sea plane, connected to the land with a floating dock, is in the water to the right of the parked planes.
