Early incarnations of the football helmet were soft, flimsy leather hats with flaps that covered the ears. Plastic helmets were introduced after World War II. Wearing helmets became mandatory in the 1930's, but logos on the side of helmets didn't become the norm until the late 1950's when owners discovered their marketing importance. It was Los Angeles Rams player Fred Gehrke, a former art student, who was the first to paint a team logo on his helmet in 1948. Cleveland Browns quarterback Otto Graham was the first to wear a single-bar face mask in 1955.http://www.buychinajerseysaz.com
