This is unquestionably one of our favorite signed photos that we've ever encountered. This oversized 16x20" photograph of Ben Hogan and Arnold Palmer smoking on the tee box at Augusta National is beautifully autographed in gold pen by both Ben Hogan and Arnold Palmer. We're not sure how many of these photos were ever signed by both Hogan and Palmer, though this is the only we've seen.
