These are truly darling pieces! They come fastened to their original foam backed pad. There is an empty space that I'm sure held a third pin, probably the animal designated from land motif. The bird being from air, and the fish being by sea. Each little design measures 3/4 of an inch but, they appear smaller yet because of the delicate composition. These little guys are in near pristine condition and would wear wonderfully on a turtle neck! Ca., 1960's-70's.
