American Dreaming is an as yet unreleased documentary on mid 20th century American car design art, the artists and designers who created it and the attempts of art collector Robert Edwards to collect and preserve as much of it as possible.
Much of this art was meant to be destroyed by the car manufacturers who commissioned it, lest their advanced designs, even the unused ones, fall into the hand of competitors.
The artists themselves saved some of the art, smuggling it out of the company offices in false-bottom boxes and by other means, rather than seeing it destroyed.
PBS has a selection of about a dozen examples on their website.
