It is, I hope those who run any of McCartney's dealings get word of it. I also think Steven is right, likely is a bait and switch tactic. There's no way you sell a $2000 record that you could easily get at auction for $600. I'd buy all of them if I was comfortable with the seller.
The Paul McCartney Enterprises site is connected to Chad Baldwin...a sorry character from Portland, OR. He did time for an armored car heist...and for selling bogus memorabilia. He seems to be quite proud of his criminality so perhaps he hopes to do more time for autograph fraud. He's used phony COA's from PSA/DNA, JSA and Frank Caiazzo.
