MMA 1984 Signed Heart Locket Necklace

This very pretty enameled heart necklace is signed inside: MMA 1984. Front of the heart is in wonderful condition, the back has some surface wear. While the locket itself doesn't attract a magnet, the chain does. Overall, this is in good to very good condition, especially for a nearly 40 year old item. :) The locket opens and closes nicely. I welcome offers and encourage bundles. Thanks!
