This is a vintage Mexican sterling silver and abalone bird brooch. It is signed TAXCO, 925, MEXICO and has 3 initials in the center but I can't read them. The brooch also has the Eagle 3 mark. The brooch measures 2 inches by 1-1/4 inches. It weighs 5.1 grams. It is in good condition but does have a heavy age patina. I have not polished or cleaned the brooch. Please let me know if you have any questions. Thanks for stopping by.
