Offered here is an actual tournament-used and autographed hat from Tiger Woods. This hat came from Tiger's exclusive memorabilia company, Upper Deck Authenticated, in approximately 2008. Tiger added a wonderful autograph to the hat, which is hand numbered 1/1. Though Upper Deck's deal with Tiger gives them the opportunity to get thousands of Tiger's autographs each year, they only receive a handful of his personal tournament-used memorabilia. The 2008 Certificate from Upper Deck that accompanies this piece states that this hat was worn in a PGA Tour, USGA, or WGC event.
