The Lancaster City Directory for 1903 listed John B. Martin (1875–1906) as a bicycle repairer and gave his address as 421 N. Prince Street, so it seems likely that this business card with the same information dates to about the same time.
I haven’t uncovered any information regarding Martin’s career as a trick rider, nor have I found any reference to the athletic grounds and banked bicycle track that he operated on Prince Street.
Martin died on March 19, 1906. He was only 30 years old and left behind three young daughters.
