Crowds around the Infant Incubator building on the Midway. Martin Couney's exhibit was located near a show by the notorious fan dancer, Sally Rand. Julius Hess, a famous Chicago pediatrician, loaned Couney his head nurse (Evelyn Lundeen) for the duration of the Exposition.
The Exposition was located on the shore of Lake Michigan, immediately south of Chicago's downtown area. Today, Meigs Field and McCormick Place occupy this site. The location of the Infant Incubator building is indicated in red.
