I bought Paul and George's autos several years ago on hollywoodmemorobilia.com and was wanting an experts opinion if the signatures I purchased is real or fake? I also have this plate that says on the back "personally signed by Ringo Starr" I'm pretty sure the Ringo is authentic, but I'm not sure about the other two. What do you all think?? Paul's auto is on a Wings album: Pipes of Peace, George is on a cut, and Ringo is on a Gartlan plate
