This one was sent to me by a BCB reader, but I also found it elsewhere, floating around the internet.
It’s obviously Wrigley Field and also obviously an old-timey football player with a leather helmet. But who?
I didn’t think it was a Bears player and looking at this page with old Bears uniforms, it’s not a Bears uniform.
The “PACKERS” visible on a jacket in the background hinted that it might be a Packers player and, checking out this page with old Packers uniforms, that turned out to be right. The Packers wore some variation of this uniform from 1939-49.
