Hi everyone, I've has this one locked away for some time. It comes from the Stanley Simmons collection. Simmons did costume work on Broadway and had connections to the Sullivan Show. I had Al Wittnebert do a hands on authentication on it. I believe that Al has one of the best reputations in the autograph industry! He noted at the time that he has never seen another example of this photo signed by a four Beatles in his career. Sadly the photo is showing signs of silvering and the signatures are starting to fade a bit. Anyone have any advise on preservation?
