A smashed guitar signed by members of Nirvana is up for auction again. The guitar was smashed by Kurt Cobain in 1989 and has an estimated value between 60-to-80-thousand dollars. But considering it was sold at an auction last November for over $486-thousand dollars, it will likely sell for more. The 1990 Fender Stratocaster is one of the featured items in Julien's Auctions latest Music Icon event which runs May 19th and 20th. Other items included once belonged to John Lennon, Paul McCartney, Any Winehouse and more.
