Puffy heart charms, so named because the charms are “puffy” on both sides, were very popular in the 1940s. Most are made of sterling silver, some with elaborate enamelling or beautiful personalized engraving.
Many had themes of love, such as Forget Me Not flowers, or lovebirds. I’ve seen them with animals, fleurdelis, scrolls, repousse styling, other floral themes and WWII sweetheart military themes.
Some of the most collectible were made by Walter Lampl, who manufactured series of guilloche enamel birthday charms as well as floral series charms.
