I have a cool early GNR contract signed by Axl, Duff and Slash. That route was very expensive, but his autograph is simple and easy to forge, so I'm glad I went in that direction.
Sadly, I agree. It is not likely genuine.
What a shame that a UACC RD only has legit items 'scattered in'...
At least you didn't buy it and have to go through the hassle of returning it. Your right though, they do have good stuff. Sometimes.
