Nirvana frontman Kurt Cobain's famous green cardigan, which the late singer/guitarist wore for the band's MTV Unplugged taping, sold for $334,000 at auction on Saturday (October 26th). That established a new record for the most expensive sweater ever sold at auction, while more than doubling the garment's sale price from just four years ago.

The olive green sweater -- complete with missing button, a burn hole and several stains -- last sold for $137,500 in November 2015 through Julien's Auctions, the same company that sold it Saturday.

Ahead of this weekend's auction, the sweater had already surpassed its $200,000 minimum bid and then blew past the item's $300,000 pre-auction estimate. The sweater was accompanied with a handwritten letter of authenticity from Jackie Farry, Frances Bean Cobain's nanny and a close friend of Courtney Love, who gifted Farry with the sweater following Kurt's death in April 1994.

Meanwhile, another Cobain item sold for even more at the same auction: his custom-built Fender Mustang guitar, used by the Nirvana frontman on the In Utero Tour, went for $340,000. The guitar, which was previously kept at the Rock and Roll Hall of Fame, came with a handwritten letter from Love stating that the instrument was one of her husband's favorites.
