This magnificent book tells the story of the most important Porsche 917 of all – the one that gave Porsche its first victory in the Le Mans 24 Hours. In 1970, the world's greatest sports car race was ravaged by periods of torrential rain, but through it all came 917-023, driven by Hans Herrmann and Richard Attwood. They achieved a landmark success for the German manufacturer. This book provides detailed insight into not only this race, but the six other races 917-023 competed in. Supported by a superb collection of period photographs, many in color, all Porsche fans will love this addition to the "Great Cars" series.
