There is, I think, something sadly ironical - and the same could be said about the 1937 Exposition Universelle in Paris - in the fact that the fair conveying most the hope and faith in The World of Tomorrow happened to be held on the very same year the almost entire world sunk into what was to be the worst conflict of modern era.
The picture is (loosely) based on the Marine Transportation Building, at the 1939 New York World's Fair. Twin ship prows, each 80 feet high (30 feet higher than the nose of the Normandie), gave a nautical flair to the main entrance. Sea effect was further enhanced by boat decks, 150 foot mast and a large basin for display of yachts and cruisers. Architects of the building were Ely Jacques Kahn, William Muschenheim and Morrison J Brounn.
