Official 2020 US Open Winged Foot Tournament Pin Flag, nicely signed in black marker by Bryson DeChambeau.

There are a four very minor pin-holes in the flag.  They are barely noticeable.   It is common practice to pin golf flags to cardboard before signing them so that the signatures  come out nicer on the flat immovable surface.  They are near the corners and are very hard to see even in these close-up images.
