The coveted fully embroidered 1997 Masters flags are worth about $2,000 and very difficult to find. So when Tiger Woods' exclusive autograph provider Upper Deck wanted to get Tiger to sign flags from each of his Major Championship victories, they had to get creative (and we would know - Upper Deck asked us if it was possible to obtain a couple hundred genuine 1997 Masters flags). So Upper Deck had Special Edition Masters flags embroidered with "1997" to match the style of all later Masters flags. 

This "1997" Masters flag is beautifully autographed in the center by Tiger Woods.
