No particular milestone associated here with this 'Look Back' pic, just a simple shot of F1 great Ronnie Peterson racing his pretty little F3 Tecno around the streets of Monte-Carlo in 1969.
'Superswede' won of course the coveted F3 support race that year in front of countryman Reine Wisell and Jean-Pierre Jabouille. Needless to say, man took precedence over machine back then, and Ronnie was already one heck of a racer...
