A 1973 Fender Mustang that was owned and played by Kurt Cobain is going up for auction at Julien's Auction. The signed guitar was smashed onstage by the singer in 1989. He didn’t have a guitar for a while after that show. It's expected to sell for somewhere between 200-and-400-thousand-dollars. If you’ve got the cash to bid with, head to JuliensLive.com.
