Vintage MOSBACHER ENERGY COMPANY Metal Porcelain Gas Oil Advertising Sign. Early Sign not often seen with patina. Sign measures 26″ in length X 3″ tall. Looks to be made of Porcelain or heavy Enamel. Sign has some dings, dents scratches and surface rust through out. Just what I like to see! Sign displays well and will make a great addition to any collection! Good Luck and thank you for looking!
