The item for sale is a circular medal object with a cartoon-like depiction of an American Indian.   There is a tab on the edge to mount the object.  The purpose is unknown, but the image of the American Indian has been used as a mascot on military insignia and corporate logos.  My guess is that the item is military because the tip of the arrow has what appears to be a missile or torpedo.  The surface of the plaque has some environmentally induced changes including darkening and some verdigris near the rim.  The reverse has an area of superficial scratches.  The details on the Indian figure show very little wear. The diameter of the object is 4 7/8".
