A charmer of an old wooden field decoy I think, which was definitely put to work—there are shot marks all over one side. I’m not an expert but think it might represent an American Oystercatcher with its bright yellow eyes and long beak, black head and white belly. All the better for the twist of old wire still attached to one side, which was threaded rather beautifully through three nailed loops. 

14 1/2" long measured straight from tip of beak to tail; 6 1/2" tall not including wire (14 1/4" t with wire); 7/16" thick. 1920s-40s I would guess. Great surface on both sides; structurally sound and stable, paint is not chipping.
