W. Guy Wall

You're looking at an image of W. Guy Wall who designed the 1912 Indianapolis 500 Mile Race winning National Motor Vehicle Company race car driven by Joe Dawson. I don't have a lot of information on Wall but he was active in Indianapolis during that era and even had a role in the 1909 National Championship Balloon Races hosted at the Indianapolis Motor Speedway. He also acted as an official at the Speedway's first motorcycle races in 1909.
