Vintage fancy tribal shield poss brass fancy statement necklace

From my personal collection. It is quite the unique piece & possibly brass. It is amazing in the design & not only the cutouts but that each piece is also hammered & each underside (pic#8) is also completely etched from top to bottom. Designers do not put this much work into the backs of their pieces anymore since no one will be seeing the underside of them. They usually put no work into the backs. Very beautiful & interesting. The chain is a thick slinky vintage one you might have seen before (pic # 9) however when magnified (pic #10) between the slats is hollow & these chains are no longer used. From top upper left bead to bottom center of the shield part measures 5 3/4". From left upper arrow to right upper arrow of the shield measures 6 1/2" It is a solid piece. Earrings match the shield & are post pierced & measure 1" H x 3/4" W Necklace is 18 1/2" - 21 1/2" I purchased it in 1990 at a vintage auction where in the box I verified my oldest items as far back as 1934. It still has a purchase tag on it. New
