Leatherheads, the movie, had some great vehicles from the 1920's... George Clooney driving a motorcycle and sidecar, and Rene Zellweger. Good movie

 I looked carefully at the motorcycle, and can't see who made it. Could be any of several bike companies

 I just learned that these were both made by Eddie Paul, Thanks to Neil Larson for sending me these!
