While the 1997 Masters flag seems to get all the love, the most difficult Tiger Woods autographed Major flag to obtain is unquestionably the 1999 PGA Championship flag. Most flag collectors agree that the 1999 PGA flag (affectionately called the "'99 Medinah") is approximately 10x rarer than a 1997 Masters flag. Flag collecting was still in its infancy in 1999, and very few '99 Medinah flags were produced. Even fewer have been autographed by the winner of the tournament, Tiger Woods. To complete a collection of Tiger's 15Major Championship flags, collectors must track down this elusive flag. This example is highly impressive, with an excellent Tiger autograph.
