A life-size diorama of the Brickyard paddock spans many decades with side-by-side garage scenes. It includes a '35 Ford-powered Indy racer, which qualified for the outside front row in 1937. This is the real car that the above pedal car is based on. Children's pedal cars first appeared in the late 1880s. It wasn't until the early 1900s that pedal cars became widespread and were readily seen in the United States. Originally called Juvenile Steel Automobiles by the Butler Brothers, their pedal cars had sheetmetal bodies, open steering, and double-spoke wheels.
