350 Fifth Avenue, between 33rd and 34th Streets. Color postcard with an idealized drawing of the Empire State Building. The image erroneously shows the mooring mast shaped like a pylon and functioning like a lighthouse, with beams streaking out of it on two sides and into the night. A dirigible approaches the mast, perhaps to dock with the building. The mooring mast was originally designed to dock dirigibles, but the wind currents surrounding the Empire State Building made it impossible.
