Oldfield Tires?

I'm stumped on this photo. Clues appear to be tires, and Harvey Firestone put Barney in the tire business with "Oldfield Tires," which means the photo could have been taken in 1920. The jockey-sized man pictured with him makes me think of the stunt aviator Lincoln Beachey, whom Oldfield barnstormed with in 1914. Beachey was killed in 1915. Anyone with better information is most welcome to comment.
