This 8 sided (rectamgle shape with flat corner edges) medal was given out from the American Poultry Association – Standard Bred Exhibition in the 1930’s – 1940’s. Overall size is 1 3/8” in height and 1” 1/8” in width. Geo. Lauterer Co. in Chicago was the jeweler of this (I believe) copper base with enameled emblem attached. In excellent condition only needs to be cleaned.
