I know and have done business with this seller. He is fairly good and, yes, the Cushing is genuine as is most of his signatures. There are some though that I would question. Always a best bet to get opinions if you are not sure.
Cheers Joe. I've asked if he knows how it was obtained and also if he would offer a money back guarantee ahould I take it to Beckett or PSA and it fails. I guess that's all I can really do?
