I would get that looked at and authenticated to see if that is actually signed. It could be a facsimile sig.

Yea, I thought the same thing when I first saw it so I looked up similar autos and looked for signs of facsimile/autopen and didn't see any. Looks like legit Sharpie marks on the backside and all. Plus the "Signed Copy" sticker eased my mind too. Goodwill is notorious for overlooking signed books so I don't put it past them, ha. But yea, I had the same thoughts you had.
