1970 - Guessing here but I believe this is Jochen Rindt (Lotus Cosworth 72C) leading Jacky Ickx (Ferrari 312B) and Pedro Rodriguez (BRM).
  Rindt won, Ickx was 3rd and Rodriguez 10th.  Rindt was killed in practice for the Italian race at Monza in Sept.
He became motor racing's first posthumous World Champion.  A YouTube tribute to Rindt is HERE.
