I don’t have much to add but wanted to share this photograph I discovered this morning while preparing for next week’s classes. Here we see a young woman standing before the Trylon and Perisphere after the remainder of their scaffolding was taken off on 22 February 1939. The World’s Fair coincided with the sesquicentennial of George Washington’s First Inaugural; President Roosevelt opened the Fair on 30 April, 150 years to the day after Washington took the oath of office in Lower Manhattan at Federal Hall. In winter 1939 Robert Moses’s crews were working long shifts to prepare the fair grounds in Queens in time to ensure the event opened on time come spring. Presumably they took the scaffolding off on Washington’s Birthday intentionally to promote the upcoming fair and emphasize the tie-in to the first president.
