Bobby Unser, 1968 Indy 500 Champ

This is David Story's rendering of 1968 Indianapolis 500 winner Bobby Unser's Rislone Eagle. Below find David's margin notes.
 
"The winning Eagle that was part of a one-two finish in the 1968 Indianapolis 500. Car #3, sporting Rislone livery and a turbocharged Offenhauser engine, powered Unser to the lead for 127 of the race's 200 laps - including the final one. The victory was never assured because of the outright speed of Andy Granatelli's turbine-powered Lotus 56 racers, all of which failed to finish the race."
