On this lovely spring day our thoughts, as usual, turn to football. Of course, there’s the NFL Draft coming up this Thursday, but we found this on YouTube — the only place this side of the Packers Hall of Fame that you can view this film. It’s “Pigskin Champions,” a 1937 sports short subject documentary directed by Charles G. Clarke. Produced by Metro-Goldwyn-Mayer, it was a part of the "Pete Smith Specialties" series, and featured the then-World Champion Green Bay Packers in an exhibition of football skills.
