Vintage 40s Silver Mexican Concha Fan Brooch Art Deco Pre-Eagle Pin

Here is a finely crafted Art Deco silver brooch from Mexico with a winged or fan shaped Mesoamerican design – possibly that of a concha or stylized maguey, circa late 30s early 40s. The pre-Eagle pin is hand wrought from unmarked sterling silver or higher, which is anywhere from 940 to 980 silver, and features an incised scalloped design along with raised silver domes – with larger dome at the center, and two smaller domes, top and bottom. It measures approximately 2&3/8 inches across, by 1&1/2 inches high, has hand wrought fittings with a c-catch, weighs 15.9 grams, and is marked “Mexico” within a rectangular cartouche.
