I am not nor ever claimed to be an autograph expert. I have always stayed out of conservations (for the most part) on someone else's collection or interest in signature authenticity as I was not there when they were or were not signed. I will leave those discussions to the much better experts on this website. I offer what I have collected in person as a tool if someone wishes and finds it helpful in comparisons. If not deemed helpful, that's their choice. I am not offended. Its just one tool (of many that are discussed on AML).
