Tom Thinesen of Sunnyvale, CA in his 1200cc.1959 Lola Mk.1 leads John Muller of Kansas City, MO in his 1600cc. 1956 Porsche "Pupulidy" Special.  

This Porsche Special's central seating position brings to mind Roger Penske's much later Zerex Special (and, of course, the "Pupulidy's" mid-1950s contemporary -- the Bobtail Cooper.)
