the guy on the far left? pretending to be interested in the hood scoop... is simply jumping into a photo of Enzo and Phil Hill, pretty clever huh!

Bernard Cahier was the go-to guy who knew everybody on the scene and behind it. People with cameras might be clicking away, and Bernard would maneuver to join not the photographers but the group being photographed.
Over time, I noticed other instances and decided Bernard was the most photographed photographer in racing.
