St. Joseph Enamel Medal Hanging Pin

This is an unusual pin.  It is a St. Joseph medal hanging on a bow pin.  You could remove it from the bow and wear it as a pendant.  It is gold ton and has purple enamel around the edge.  On the front is Joseph, Mary and Jesus as a young boy.  On the front it reads: That All May Be One, Justice, Humility, Purity, Saint Joseph Our Protector Pray For Us.  On the back at the top is a bird pointing down to the top of a shepard's hook and there are two crossed keys and a sheep family of three.  It reads: Feed My Lambs, Feed My Sheep, The Spirit Of The Lord His Guide.  There is wear to the plate.  It is a lovely piece.  The medal measures 1 1/2" x 1 1/8" and the little bow pin measures 1" x 3/8".
