Hey Marc - these are great shots - bring back so many memories. I was really delighted to see the very first one in the Keke series was of him at Lime Rock in a 1978 Chevron B45. He finshed fourth in that race and I am lucky enough to own that particular car. Its almost finished in restoration........but I have been saying that for months now - but it is very close.
Minor point - one of the Quebec City shots should be labeled as 1978 not 1977 because the car is the B45 model introdiced in 1978. The appendage on the nose of the QC race is of aerodynamic significance.
