Offered here is the 1997 book Training a Tiger, which is autographed by both Tiger Woods and Earl Woods. Very few dual-signed Tiger and Earl Woods items exist, and these autographs are exceptional. This book was almost certainly signed upon the book's release in April 1997, as Tiger's autograph changed shortly just a couple months later.
Authenticated by both JSA and PSA/DNA. Comes with a Letter of Authenticity from James Spence Authentication (JSA). Also contains a PSA sticker inside, but the accompanying letter is missing and will need to be replaced by PSA.
