On May 30, 1911, a 29-year-old race driver/engineer nicknamed ‘The Little Professor’ came out of retirement for one last event, which happened to be the very first running of the Indianapolis 500. Harroun won the race in a time of six hours, 42 minutes and eight seconds at an average speed of about 75 mph. Harroun’s winning car, a black and yellow pointy-tailed Marmon Wasp, is currently on display at the Indianapolis Motor Speedway Hall of Fame. The original Wasp is priceless, but anyone can order an exact 1:18-scale-model replica (about eight inches long) for $230 from Replicarz of Rutland, Vermont. Ordering details at www.replicarz.com.
