I was doing just the same thing today before I bought a book over E-Bay. It was the chronicles by Bob Dylan. Supposedly signed. I battled over this one to be an authentic but I thought it couldn't be because I don't think Bob did many book signings and I searched for other autographs and they didn't measure up for me, to make this one look authentic. I suppose for the price it was at (85.00 US) it may have been a good price, but I was doubtfull. Hope I don't kick myself in the ass someday finding out it was the real thing.
