Mike Rogers writes: "In a move that can only be described as "Copyright Insanity", Form Motor Company now claims that they hold the rights to ANY image of a Ford vehicle, even if it's a picture you took of your own car. The Black Mustang Club wanted to put together a calendar featuring member's cars and print it through CafePress, but an attorney from Ford nixed the project, stating that the calendar pics and "anything with one of (member's) cars in it infringes on Ford's trademarks which include the use of images of THEIR vehicles." Does Ford have the right to prevent you from printing images of a car you own?"
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
