I have a copy of this image but this looks to be a real one.
Background: In 1937 the Washington Herold Times honored the Redskins Championship win by putting a team signed photo in every newspaper one day.

If it's real like I think it is it will go for far more than the $61 it is sitting at now.
You can see in my collection I have a copy of that same image but mine is grayish and not brownish like a real photo would be.
