To me, authenticity aside, this has nearly terminal contrast problems. That's just me and I may be overtly picky - what do others think? I sit back a bit in my chair and I can't even see this autograph.
I think it's good, but it's really rushed and abbreviated. I also agree about the bad contrast. For comparison, here is a telecaster signed by Mick Taylor that I obtained in person on the Stones' 50th tour.
