July 18, 1925. Prince George’s County, Maryland. “Bicycle races at Laurel Speedway.”
very cool photo showing some young and some older riders. Amongst all the Columbia and Iver Johnson bicycles, looking into the details you see a couple of bikes with brake levers and even one that has a pump mounted on the seattube(4th bike in, that some have wondered if it is young Bobby Phillips Sr.??).
