Photo from Ron Mann, Pennsylvania Hillclimb Association Historian.
Photo taken at an autocross track near Bernville, Pa.- Christmas Village gocart track- now defunct. The other two cars are Randy Ravel in the DKW-Mitter Formula Junior, and Denny Gawrys in "The Blue Goof"- a Saab powered Spitfire with custom, albeit crude bodywork. Carrol Shelby once drove the Mitter, and called it the most unsafe car he'd ever driven.
