A large vintage or antique sterling puffy heart charm or pendant that is a cross-over collectible piece, as it is also a whistle in a rare heart form! Miniature whistles and in particular sterling whistles are a collectible in their own right, as are puffy heart and this one checks both boxes. The heart is marked sterling along the back the way that puffy heart charms are. It measures 1 1/8" wide and 1 1/4" high not including the bail. It has a beautifully done monogram on the front. It may be MCW. I am sure of the M and the W. The whistle is completely functional. The charm pendant whistle is in excellent condition with no scratches or dents. It came from the estate of a lifetime collector of antique whistles. It weighs 5.5 grams.
