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.
I just uploaded the last piece of content I currently have on file of the Indianapolis Motor Speedway's June 1910 aviation meet. This entire collection is the best bundle of first-hand newspaper coverage you will find anywhere on-line concerning this interesting and historic event.
