Kurt Cobain’s smashed Fender Stratocaster guitar sold at auction for $595,900, more than 10 times its original estimate. The Nirvana frontman’s iconic left-handed electric guitar was smashed while the grunge pioneers were making their seminal Nevermind album in the early 1990s. Reassembled but unplayable, it was expected to sell for between $60,000 and $80,000 at the Julien’s auction at the Hard Rock Cafe in New York over the weekend.
