Thanks for the info - I am enjoying this thread.
I agree same pen and same date, but "Here, please sign this" and then Smith immediately adding the date and location using the pen in his hand that Jackson just returned seems perfectly plausible to me. And, to me, there is nothing the same about the signature and the rest of the writing. But - I am not a handwriting expert.
I did read the old thread (
https://net54baseball.com/showthread.php?t=201313). There it says that HA noted the inscription as being in the photographer's hand, so maybe my hope for some of Smith's writing in the album Rhys now owns will come to pass.
There are also people in that old thread that questioned the Matty signature, but as I pointed out in post 135 in the current thread, after seeing the 1911 newspaper premium, logic dictates that the Matty is almost certainly legit.
I still see a ton of variation in all of the known to be legit signatures, and the 1914 and 1916 PSA examples (
https://www.psacard.com/autographfac...oe-jackson/21/) on documents look somewhat fluid. His later signatures get much worse, but that happens to tons of people as they age, and I would guess more so if they write very little.
