Cute Vintage PARRA 1940s Mexican Sterling Malachite Duck and Duckling Brooch Pin

Cute as can be! Circa 1940s Mexico Mexican Parra Sterling Mama Duck has a little duckling waddling behind her. Mama is 1.5 x 1.5" Baby 3/4" x 3/4" approx. Original deep patina ( I don't ever shine up vintage sterling as all collectors have there own preferences as to the patinas they desire on them) This has been in my collection for a very long time....hope it will find a great new home
