The attachment below contains three interesting articles all appearing on the same page of the March 23, 1910 Indianapolis Star. One of the articles discusses the final day of racing at that year's Daytona-Ormond speed festival. The same article appears elsewhere on First Super Speedway and you can find my analysis there.
I never thought I would see any of this film as I thought it was lost forever. Captured here in what is called a "Rare Jack Johnson Documentary" at the 26 minute mark is film from the infamous October 1910 unsanctioned match race between Barney Oldfield and Word Champion Heavyweight Boxer Jack Johnson. I think the film producers dramatized the contest making it appear closer than it was. It appears the same clip is used over and over to make the finish appear closer than it was. What is more the contest was in two heats, not one.
