Andrew Garfield and Emma Stone sign rare comic for charity

Spider-Man stars Andrew Garfield and Emma Stone have shown off their caring sides by signing a rare comic book to raise funds for charity.

The actors autographed a copy of Spider-Man #6, which was published in 1963, alongside the signature of filmmaker Marc Webb, who is directing next year's (12) The Amazing Spider-Man.

The comic is now being sold off on auction website eBay.com to raise funds for Stand Up To Cancer.

The sale ends on Saturday (09Jul11).
