This is a classic picture that depicts a 1957 Maserati being worked on by the drivers mechanic before a race. There is an a certain casualness about this scene as the car undergoes a few checks and tweaks before the race. It is critical that everything be in perfect running order to minimize any unforgivable mishaps during the race..at least mishaps that can be controlled by the mechanic to some extent. A few others in the background engage in casual conversations discussing the race, the competition, and the strategy to win.
