RARE! Enamel on Copper Pendant - Vintage

Beautiful vintage artisan crafted enamel on copper pendant with original romance card and signed by the artist (on copper back - see photos). This is a true fine art piece - an investment piece. Approximate measurements: pendant (not including bale) 2 1/2" long; 1 1/2" wide; 3/8" bale length; 1/4" bale opening. Generous-sized bale allows for a wide variety of chains, ribbons, leather, etc. materials for wearing. Enamel on copper is a very time-consuming and difficult art form. Wearable art!! Offers welcome.
