Offered here is a genuine Tiger Woods backup putter that Tiger himself auctioned at his charity event Tiger Jam in 2008.

Like Tiger's legendary gamer, this Scotty Cameron Newport II GSS has a big red tour dots, vertical Scotty Cameron face stamping, and TIGER WOODS on the rear bumpers. Just before the charity event, Scotty Cameron took one of his backup heads that he made for Tiger and stamped TWF08 on the toe, which stands for Tiger Woods Foundation 2008. 

35", with a Scotty Cameron signed Pro Platinum headcover, 9.5+/10 due to minor marks on the hosel, and extremely minor marks on the head.
