OK. That's the one in which you said that a "small bit" of the ink has to be removed. How much is a "small bit," and how would it affect the signature? And how specific can it nail down the range of time that the ink was on the paper? Because I'm thinking that if it can give a definite range within a few years give or take of 1911, it would go a very long way to authenticate the signature. Other than his wife, who had a distinctive way of signing his name, who else would be putting his autograph on a photo? Who else even knew what his signature looked like? Assuming that the test doesn't do any visible damage to the signature, it would definitely be a worthwhile venture.
