Wikipedia states: "The 49-Mile Scenic Drive is a designated scenic road tour highlighting much of San Francisco, California. It was created in 1938 by the San Francisco Down Town Association to showcase the city's major attractions and natural beauty during the 1939 Golden Gate International Exposition." We state: "That's a hella long drive." Patch measures 3.90" X 3.25". We use HeatNBond Ultrabond iron-on backing, but we advise our customers to use the iron-on backing at their own discretion and cannot guarantee that it will stick to all fabrics.
