Weed Tire Chains Sign, circa 1925

This circa 1925 sign has a dual purpose -- to alert potential customers to the price of gas, and to advertise the necessity of "Weed Tire Chains." In 1904, Harry D. Weed was issued a patent for his "Grip-Tread for Pneumatic Tires," a non-skid tire chain used to increase traction on roads slick with mud, snow, or ice.
