Photograph taken from an album of images compiled by English motorist, motor car manufacturer and aviator Charles Stewart Rolls (1877-1910), showing two tricycles about to compete in a race in which Rolls entered his de Dion tricycle. Rolls founded Rolls-Royce Ltd with Sir Frederick Henry Royce (1863-1933) in 1906, creating one of the world's most famous marques. He was well known on the motor racing circuit, competing in many of the races of the time. He was also the first to make a non-stop double crosing of the English Channel by aeroplane.
