Has someone who bought his wares verified his two galleries? I have seen a lot of art I really like, and still thought it was over priced. Doesn't mean other people didn't happily pay for it. Art is subjective and worth what one person is willing to pay for it.
No. The galleries and being a famous multi million dollar engraver were just part of his facade and scam. If this guy wanted to prove anything he could just show a short video of his galleries or one of him actually hand carving his intricate designs and everybody would be left eating their hat, but he hasn't so far.
