I think it would be fun to assemble a picture/video archive representing movie-stars, musicians, politicians, etc ... on a BIKE. My pick is from Butch Cassidy and the Sundance Kid (1969). Pictured here is Paul Newman and Katharine Ross. One of the great classic scenes of Hollywood. Any more contributions to this thread are welcomed.
Yay, Paul Newman! On the ride home tonight, I had "raindrops keep fallin' on my head" going through my head the entire time.
My favorite celebrity on (or next to) a bike picture is Ellen Page with the same bike as mine.
