Crosley was a major manufacturer in the late 1930's -- making everything from radios to refrigerators -- and, of course, minicars.
The picture above is a publicity shot, taken in front of the Crosley Pavilion in the World of Tomorrow section of the fair. Rides were given to guests of the fair on a short course just outside the pavilion.
There is a brief clip showing the cars and the pavilion twelve miutes and fifty seconds into this amateur film.
