After watching it for a few days, and a little research, I decided to just jump on the low BIN.
The Sipsey Mine Team from the Birmingham Industrial Leagues in the 30's.. Front row, 2nd from the left, is apparently Huey Green, father of World Golf Hall of Famer, and 1985 PGA Championship winner Hubert Green..
Lucked into part of an article from 2004 about the Industrial Leagues, that just happened to use the photo..

Not sure if anyone else in the photo is notable though..
