François Cevert was so hard to read. Half the time I look at this shot, I think he’s giving an intimidating glare. The other half of the time it looks like we’re sharing an inside joke. It has to be one of them though, right? There’s either a set jaw or a smirk behind that balaclava.
Edit: Thanks to Kev for identifying the photographer of this marvelous shot as Rainer Schlegelmilch.
