Was looking at that copy and asked a bunch of questions. Wasn't too comfortable buying the book by looking at his past feedbacks (video games, video game consoles, fitbit, etc.). No history of him selling any comics at all. Also asked for any references from any major dealers or collectors, he ignored that part of my question.
Book sold for $20k from what he messaged me and mentioned it came from a dealer. All I know. Still looking for a copy
Seller first listed the book raw. 25K BIN price. Didn't sell so he wisen up and had it slabbed.
