This vintage fold-out map is a rare find from the 1934 Chicago World's Fair, also known as A Century of Progress. The map was produced by the Chicago Surface Line and features a stunning visual representation of the fairgrounds and surrounding areas in Chicago. It is a must-have for collectors of historical memorabilia, especially those interested in world's fairs and early 20th century transportation. The map is in excellent vintage condition, with some slight signs of wear that are to be expected from an item of its age.
