Brought to you by Museum of American Speed in-house historian, Bob Mays: "No form of American auto racing has a longer or more prestigious history than the dirt champ car. No form of racing photography has a longer or more respected history than the posed photograph. 'Competition Portraits, The Dirt Championship Cars,' follows the history of the big car from 1946 to 1987, featuring some of the most recognizable stars and cars from the greatest era in racing. The good, the bad; the winners, the losers; the champions and their chariots, are featured in the moments before the call to fire engines. Many of the best shorts from the top photographers in the history of the sport are presented in a format that lends itself to the study of the man and a critical analysis of the machine just before the battle on some of the most impressive speedromes ever carved into the earth."
