Vintage Sterling Save the Children Brooch on Card Vintage Pin

Sweet vintage sterling silver Save the Children brooch. Fun impressed design on asymmetrical rectangular brooch, on the original plastic card. Brooch measures 2 1/4" x 7/8" at widest and weighs 8 grams on my scale, excluding the card. It has heavy tarnish but is in very good vintage condition. Marked on back with an EFS copyright along with Save the Children, 925 and Mexico.
