Pianos, guitars, masks, clothing and… em, fake teeth, were among the items being auctioned at the Idols & Icons: Rock and Roll Auction in LA last weekend.
The collection of ridiculously-rare items were collected by Julien's Auctions, 'the auction house to the stars.'
The teeth up for grabs were worn by Michael Jackson in Thriller and the instruments were among those used by John Lennon, Ringo Starr, Elvis Presley and Nancy Wilson.
There was also the mask that Lady Gaga wore in her Bad Romance video.
But most notable, was Kurt Cobain's cardigan, worn in the 1993 MTV Unplugged performance that won a bid of more than €128,000.
The green mohair cardigan is an item that many fans say defined Kurt as he wore it during one of Nirvana's best live shows. The Grammy-winning performance was one of the band's final performances before Kurt's tragic suicide in 1994.
Other major bids on the weekend included John Lennon's acoustic Gibson J-160E quitar, that sold for €2.2m. three times the estimated bid.
