There is a real decent chance that is Ty Cobb. The face structure - from the same exact 'bends' and what not of the ears, the tension lines in his cheek and by his mouth, and the teeth-gritting snarl - is a near-perfect match (I tried to photoshop it a bit to release hidden details, but nothing 'new' was revealed). Obviously, I could be wrong. Since other pictures exist of him in a Cleveland jersey, there's no reason to conclude it was taken on Addie Joss Day. There's got to be a bizarre reason behind him wearing that uniform on other occasions. Certainly, the rules governing attire were way looser back then, so who knows what was going on??

You should 're-Cartesian Circle' that guy and say, "You didn't witness every uniform Ty Cobb wore, so how are you able to say the pic could only be from Addie Joss Day???"

Not sure if it's been mentioned before, but the biggest dispeller of this photo originating from Addie Joss Day is that big white building in right or right center. As far as I know (not much on this subject), nothing like that appears there in the 'Joss Day' stadium, so wouldn't that prove the case?
