BMW's world Art Cars have been around since 1975, with some of the world's most famous artists taking turns to adorn examples of the Bavarian cars with their own unique design work.

A tour of the 16 rolling works of art has already arrived in North America, with an exhibit opening today at the Los Angeles County Museum of Art (LACMA). Four of the project's most famous works, those of Andy Warhol, Frank Stella, Roy Lichtenstein, and Robert Rauschenberg, will be on display, free of charge, in the BP Grand Entrance, from February 12-24, before they head off to New York's Grand Central Terminal from March 24-April 6, en route to three locations in Mexico thereafter.

The display is complemented by a behind-the-scenes video of the artists at work, which you can view along with the press release after the jump and the images in the gallery below, but if you're in the LA area, we'd suggest stopping by the LACMA to see these spectacular mobile works of art for yourself.
