Kurt Cobain’s left-handed Hangstrom Blue Sparkle Deluxe guitar is up for grabs, via an eBay auction.

The guitar is the real deal, with Nirvana’s former guitar tech Earnie Bailey reassuring GeekWire that he “hand-delivered the 1958-era instrument to Cobain in Seattle in 1992 at the musician’s request.”

10% of the sales will go to Transition Project Inc., a Portland charity which assists homeless people find housing – a worthy and relevant cause, considering Cobain often bounced around from house to house during his teenage years.

No idea what kinda cash you need to fork out for such a rare piece of rock memorabilia (remember, each time he smashed the bejesus out of a guitar, the ones he didn’t smash became that much more valuable), as you need to pre-quality just to bid.
