This is a two-part series of articles that ran in the Saturday Evening Post in 1925. They are an autobiographical overview Oldfield wrote with the assistance of William Sturm. I judge some of this material to be inaccurate, not because Oldfield embellished (not that I put it past him), but because I think he simply forgot things.
This video is the fourth in a multi-part series on the history of auto racing and primarily focuses on the Indianapolis 500 from 1919 through 1921. The footage is absolutely fantastic, with several scenes of what would be unthinkable today - drivers and mechanics pushing disabled cars along the inside apron to get them back to their pits.
