Webb Jay and Augustus Post driving White automobiles

Two views of White cars. Top image shows Webb Jay driving White racecar, known as "Whistling Billy"; bottom image shows Augustus Post driving 1905 White steamer. Typed on back: "The famous White racer shown in this picture was known far and wide as 'Whistling Billy,' and its feats on the track back in the early part of the century were nothing short of amazing. This speedy steamer, with Webb Jay at the wheel, won the National Circuit Championship at Morris Park, New York, July 4, 1905, and lowered the world record for the mile to 48 3/5 seconds. Augustus Post, chairman of the Touring Committee of the American Automobile Association, at the wheel of his 1905 White steamer in the well-known New York to St. Louis tour which took place from July 25 to August 10, 1904. White's new 1905 model had just been introduced the previous month. Ten Whites were awarded certificates for successfully completing the tour in accordance with contest rules. Victories of the 10-horse power White over many competing vehicles of 24 horse power showed that the comparative speed of cars could not be determined on horse power alone."
