1999 Masters Flag

1999 Masters flag taken from the 1999 masters tournament. Signed by 5 previous masters winners including one of the greatest to ever play the game Gary Player. Also includes Byron Nelson, Watson, and Jack Nicklaus. Im not sure who's the 5th signature is. My father was a commentator for ESPN for 10 years he went to cover the masters at Pebble Beach multiple times and picked this up in 1999. Ill have to do some more research on the exact signatures. I know for a fact one is Gary Player, Byron Nelson, Watson, and two other players who again all wore the green jacket at least once in there career I know that much. This is not PSA graded so I know it wont be worth as much, but I have proof that my father worked at ESPN and covered this tournament. It even has his play card inside where my dad did 18 holes while he was there after the tournament concluded. Anyways it's authenticity is undeniably especially to any memorabilia collector. Im asking at least $400. Who ever buys this weather its for your own collection or you want to send it to PsA to get graded so you can turn around and sell it for 4 times that .
