So here's the 3 I own with the similar pose for reference. With those muddled pics of yours, I don't think I'd buy anything quite frankly.
I am 50-50 on this one leaning towards no? The only thing I'm sure of by your pics is that it's effin cold as hell where you are and you have a Joe DiMaggio brain freeze. It's 72 here all week!
I just always HATE that "JAI" Dimaggio. Look at these signatures on these 3 photos I posted and go for something like that where you can clearly see they were signed with authority. Look at the pen signed signature where the "e" and D meet...Look for that interaction. Personally, I'd keep looking.
I will have to defer to shells opinion above as he has forgot more than I know.
ALSO important to note: Look where he signed my 3 photos of that same pose...ALL in the same place. The one you posted is signed way over to the right and that's probably not the biggest tell, but one of the major ones.
