Bought this off of Ebay several years ago. Tiger missed the cut for this tournament, and I have not seen another one like it. The seller was not an autograph seller and this was an in person autograph (the only one that the seller has ever sold). The slant, pressure, size, and speed for such a difficult item to sign leads me to believe it is genuine, considering I have seen plenty of authentic signed hats go for under $150 lately. The signature is also comparable to that of an in person pin flag I obtained around the same time period.
