Music Hall / Music Building at the fair, described on a postcard as follows:
The Music Building is modern and functional in design: of fireproof construction, and is equipped with the latest stage mechanisms and appliances. The auditorium is egg-shaped, without balconies or interior columns, and thus affords perfect vision. The square end of the building which rises to a height of 80 feet houses a magnificent stage from which many impressive musical presentations will be given.
The postcard (different art on the end):
A look inside, which included an “egg-shaped” auditorium:
American Art Today Building, New York World’s Fair Source: NY Public Library
Rendering of a the Contemporary Arts Building, also called the American Art Today Building because that was the name of the exhibit. I imagine it was filled with all kinds of modernist art.
Pretty sure George Washington was the biggest sculpture at the fair. Look at the second picture and for scale check on the person sitting at the base. This sculpture stood at a the end of a huge reflection pool, which was lit up at night, and backed by the Trylon and Perisphere.
“Mithrana” by Albert Stewart, New York World’s Fair Source: NY Public Library
The archive doesn’t provide info on what building this sculpture appeared on, but I looked it up and Albert Stewart was the man behind several well-known architectural sculpture, including friezes at Buffalo City Hall
“Europa” by Gleb Derujinsky, New York World’s Fair Source: NY Public Library
Rather over-the-top sculpture by Russian artist Gleb Derujinsky, father of famous fashion photographer Gleb Derujinsky. These look like construction photos and imagine during the fair the basin would be filled with water, with the dolphins flying over it.
