It's a given that most artists struggle to make money with their art. In the '60s, several of them called attention to the struggle by duplicating dollar bills and other legal tender and otherwise making money the focus of their work. David Wojnarowicz gluing Xeroxed bills to a pig's skull is an example. Another is Andy Warhol's photo-real replica of a dollar bill.
For decades, photos of a huge, face-shaped rock formation on Mars sparked thoughts of intelligent life -- or even a statue of Elvis on the Red Planet. But now the European Space Agency has unmasked the face -- as not really a face at all.
ESA's Mars Express has obtained images of the Cydonia region, site of the famous 'Face on Mars.' The High Resolution Stereo Camera photos include some of the most spectacular views of the Red Planet ever.
