The car, which was displayed at the 1957 Chicago Motor Show, had been all but given up for lost. In fact, it was hiding in plain sight, still in a garage, still in Chicago and in the hands of the second owner who had bought it in 1960.
Sloppy handwriting had resulted in the misreading of the owner’s last name and sent searchers on wild goose chases over the years.
