To answer your question! As far back as I can remember Leland's is as honest as they come. Very reputable and very trustworthy. Do you have a clearer picture of the Robinson Autograph
I agree with John. Everyone makes mistakes, though, so it's good to verify authenticity, especially at auctions, because they often don't have a return privilege.
I wish it was a clearer picture, but when I glanced at it, I'm seeing the positive tells that's letting me know that it's real. Look at this authentic one. Compare it to the one you posted. I'm not quite 100% there yet but..........lol.
