""The official title of the 1933 World's Fair in Chicago was A Century of Progress International Exposition. The Fair was organized to mark Chicago's one hundred year anniversary. The mission of the Fair was to demonstrate the significance of scientific and technological discoveries to industry and modern society and how those discoveries were being made. The Fair also showcased modern advancements in art, literature, and architecture from across the globe. Exhibits from all over the world included new automobile designs, houses of the future, and babies living in incubators. There was also an abundance of international carnival entertainment at the Fair, including the Skyride, a cable-suspended people mover higher than any building in Chicago. The midway provided games, a roller coaster, shows, and food. "" (encyclopedia.com) This is the Social Science Hall. These pylons represent fire, light, night, and storm. It is by Leo Friedlander.
