In 1917, three of the most famous daredevil drivers were veterans of the Vanderbilt Cup Races; Barney Oldfield (1914 & 1915), Louis Chevrolet (1905,
1908, 1909 & 1910) and Ralph De Palma (1911,1912, 1914 & 1915). On August 17, 1917, over 40,000 spectators came to Sheepshead Bay Track in Brooklyn to watch match races among the three drivers.
As described in VanderbiltCupRaces.com, three match races were scheduled at 30 miles, 25 miles and 50 miles. If each driver won a race, a 10 mile race would be added to determine the champion.
Although it had not been previously been identified on YouTube, this is a film of either the 30 mile or 25 mile race held at Sheepshead Bay.
