And you can tell they're legit: as part of their newly launched eBay site, Sotheby's are auctioning off authentic prints and multiples from some of the world's most famous artists in a sale called Meet the Press.  It's a diverse line-up, featuring works by Marc Chagall, Marcel Duchamp, Jeff Koons, Keith Haring, Andy Warhol, Roy Lichtenstein, Henri Matisse, Damien Hirst and Salvador Dali, among many others.

If you're expecting bargain basement prices, you'll be disappointed: prices start at around US$2000 for Max Beckmann works and soar to US$120,000 for a signed Picasso. Tempted? Bidding opens at 6pm ET on April 20.
