Streator, IL is listed as having a D-level minor league team in 1912 (Speedboys) and 1913-15 (Boosters). I don't have any kind of reference for their uniforms, but baseball-reference.com has rosters for the 1912, 1913 and 1914 teams (with lots of question marks). Dan Tipple (1912) and Bill Ludwig (1914) are the only ones shown to have made it to the majors:

That said, without something to compare the uniform to, I don't know if this is one of those teams or not. It's just a "could be" from me at this point, but maybe others can confirm or deny.
