I love whoever made this puzzle so much--such a clever and brilliantly executed thing, I think!. Though I've photographed it in two segments, all of the pieces fit together to form one long linear whole, with the cutout at the left of each piece fitting one particular beak. Great old paint, terrific color, beautifully aged, just fabulous. 1920s-40s I would guess.
20 1/4" long x 3" tall x 1/8" thick when configured and in great condition.
