Have a hankering for some rock & roll leftovers? The Gotta Have It! Rock & Roll Pop Art Auction is currently being housed at the Rock & Roll Hall of Fame Annex. You can check out the catalog, and bid online, here, where you'll find everything from Eminem's King of Pop costume to The King's rings... and inexplicably a T2 prop. The auction runs through August 5th, so if you have any desire to own answering machine tapes holding naughty messages from Madonna, act now!
