Indianapolis 500, May 1968

Dave Friedman has captured and preserved auto racing history through his photography. His work -- and his collection of works by other photographers -- documents key races, vehicles, drivers, teams and associated events. The 1968 Indianapolis 500 saw three unconventional, turbine-powered vehicles in the field -- two would start in the first row. However, it was a rear-engine, piston-powered car piloted by Bobby Unser that won.
