This is the rare official embroidered 1999 US Open flag from the epic Payne Stewart - Phil Mickelson duel at Pinehurst. If you've seen these flag offered before, there is a strong chance that it was a recent knockoff. This is an authentic original embroidered flag that was sold in very limited quantities at the 1999 US Open. This was before the flag collecting boom, and very few were produced. The reverse of the flag contains the original Miller tag.
