But if there's a way to show conclusively how long the ink has been on the paper (without damaging the signature), that would go a heck of a long way to show that Joe signed it. I doubt anybody in 1911 was thinking of forging his signature on a photo.

The dryness test I mentioned judges how long the ink has been on the paper. It's a standard test.
