This is an official embroidered pin flag from the 2000 US Open at Pebble Beach. Jack Nicklaus said goodbye to Pebble Beach and the US Open in 2000 - famously sitting on the fence admiring the view as he waiting to tee off on the 18th tee box for the final time. This flag is autographed by Jack Nicklaus.
