This plexiglass Pontiac, from the very earliest days of plastics, was a big hit at the 1939 New York World's Fair; it is shown here doing its star turn in the General Motors pavilion at the 1940 International Columbian Exhibition in San Francisco.
In 2011, it was auctioned by Sotheby's for $308,000. It was still a working automobile at that time, though the plastic chassis (body by Fisher) obviously would not hold up under heavy use. The odometer reading was 86 miles.
