3. The photo itself has great providence...not the signature on it.

4. The Js on the photo are smooth and I have yet to find a JJ signed document where they are smoothly formed like these. Also very small/narrow top loops.

5. It seems very likely that the same hand wrote everything on that photo and Jackson 100% could not have done that.

6. He ended his signature almost always with a downward stroke and not an up stroke like on the photo

Jackson's real signatures are very consistent through out time and this photo is not consistent with them.

Im sure better experts can point out more issues but these are the ones I would point of.

Here are a few examples I threw together, these are not to scale as the 1911 photo is much larger than any of the others.
(also notice the change in Buck Weaver's signature from 1917 to 1920-21...his signature is a lot harder to judge if you ask me)
-1915 doc
-1911 photo
-1917 team signed document asking for WS bonus money
-1920-21 court document

Could you be more specific about why you think all the writing on the photo is in the same hand? To my completely untrained eye, I can see where the signature and the rest look a bit different.
