Vintage Cabinet Photo

[Drasher99]

I was wondering if any of the uniform experts could give me a hand with this one. I picked it up on Ebay not noticing that the players were wearing numbered uniforms. From what I can find the first team to try this idea was the 1916 Cleveland Indians. It seems that this team photo looks to be earlier than that, even by the style of belts they are wearing. Any help on this would be appreciated
