Vintage Art Deco Sterling Silver Cameo Bow Brooch Pin

This piece is kind of a late run on the Art Deco period and design: based on the materials and construction, I would estimate it to be 1940’s to possibly early 50’s. It is 2 tone filigree: gold vermeil over sterling silver with rhodium to prevent tarnish. The blue and white faux jasperware cameo is plastic. Marked STERLING as shown on the reverse 2” long A touch over 1” across the bow 7/8” across the cameo drop 3.9 grams It is in excellent vintage condition. Glue residue noted on the back only: this is definitely as it rolled out of manufacturing. None viewed from the front!
