The 1939-1940 New York World’s Fair was the first exposition to be based on the future, promising visitors they would be looking at the “World of Tomorrow”. The opening slogan “Dawn of a New Day” reflected the new horizons the world would progress towards, in particular with technology and architecture. The diamond brooch reproduces the Trylon and Perisphere buildings, designed by Henry Dreyfus, which were the epicenters of the fair and great examples of High Modern architecture. It was the geometric shapes, sweeping curves, and Art Deco influences which paved a grand vision of future American architectural aptitude.
