These serving spoons, called Stuffing Spoons, were sometimes referred to as Platter Spoons and also Gravy Spoons. They are fairly large, varying in length from 11 to 13 inches. Some have a "button" on the back of the handle to keep the spoon in place as it rest on the edge of the platter or bowl. On early pieces, these buttons were very ornate, fashioned as an acorn for example, but as times changed and the art left the flatware business, so did they detail of the "buttons".
