Original Grape Nut Flakes Cereal Lithograph Advertising Sign, Grape Nut Flakes cereal was made by the Postum Co., of Battle Creek, Michigan, a Division of General Foods. The sign is 21" by x11" and is mounted on acid free foam board that has been shrink wrapped for protection. The sign is cardboard and marked "Litho in USA Form 8483." Colorful graphics and excellent subject matter. The sign is new old stock. It has never been posted or displayed. It was originally printed for use in the overhead of an old street car or trolley, thus often referred to as a trolley sign. The only thing keeping it from being classified as mint condition are two small discoloration spots on the left within the border and top right corner has a slight bend.
