I am the owner of the above image, Joy Ride: 1924. It was among my father's personal photographs. Needless to say, I was disturbed to find it posted publicly at http://detonate.com/shocking-historical-photos/38/
I know that SHORPY would not sell my upoaded image and wonder if anyone can tell me how I can get this site (detonate.com) to remove it.

Not only did they invent radar, they invented computers and scanners and the Internet. Bwahaha. View full size!)
