Sticking with the year 1963 here is a set signed on the back of a Chris Barber ticket stub. They look pretty good to me however Paul’s signature looks a bit different from what I would expect. Any other thoughts?
I think the Paul is good. I guess it wasn't signed in a controlled environment. He probably signed on an unstable surface. It seems that he tried to sign at first with Lennon's pen (thats why there are 3 P's under Lennon) and then he changed pens.
