Postcards from Detroit captures the uniquely American atmosphere of the Detroit Grand Prix and a bygone era in Formula 1 racing. With the landmark Renaissance Center as a backdrop, Roger Hart's compelling black-and-white photographs and accompanying recollections convey the relaxed camaraderie among drivers and a sense of fun that is hard to imagine in today's more intense paddock area: Nelson Piquet playing Frisbee and practicing soccer; Jacques Lafitte laughing uproariously over a joke made by Keke Rosberg; mechanics casually sprawled alongside their cars, just waiting for the next session to begin.
