I'm pretty sure that's Mike Mitchell in the upper left (#1 in top row). He didn't make the majors until 1907, though he played in the minors from 1902-06. According to baseball-reference, he played in Cuba with the Reds in 1908 and the Phillies in 1911. If one of the last two guys in the top row is Finners Quinlan (which is plausible but not certain -- compare the Zeenut and the newspaper picture of Quinlan below), then this can't be any earlier than 1908, when he first played professionally. This rather detailed bio of Quinlan doesn't mention anything about him playing in Cuba, but that doesn't necessarily mean anything: https://finner68.wordpress.com/2017/...-ww-i-veteran/
