A guitar signed by Robert Pattinson has been put up for auction for charity.

The ‘Twilight’ star was checking out instruments at a store in Tarzana, when the owner of the shop requested him to autograph a guitar.

Also, the owner snapped a picture with the actor.

The guitar was later put up for sale on internet auction site eBay.com with the starting price of 1000 pounds.

The money fetched by the sale will be forwarded to Los Angeles-based homeless charity, The Midnight Mission.

People can make their bid till 20 March.
