Paulcpick,
It looks real to me, but as FreddyE stated, inquire if the author signed the books. I have a friend that forges celebrity signatures and she's good at it. She just does it for fun if somebody asks her to do it. She's never scammed anyone, but my point is that there might be people that would.
If I purchase something with a signature, I try to get a certificate of authenticy if possible or purchase from a reliable source. I realize that you couldn't in this case. Anyway, good luck with your books.
Now if I could just find a way for authors to sign all the e-books that I've bought...
ps - Nice looking family, I grew up in Woodville (Tyler County).
