I've had this for over 30 years. I am thinking it's a copy of the original that was sold on Heritage Auctions. I can't tell if the ink is live or not, I'm leaning towards not. Anyway, I am including pics of the Heritage Auction (darker black ink) and mine. Then signatures are 100% identical. Anyway, ease my mind and let me know if you'd be so kind.
Just to clarify, the first two pics are from Heritage and the second two are mine.
Looks like a copy
