Iconic Mexican MCM Bracelet

Classic Taxco/MCM Mexican mask motif panel bracelet in rare blue glass. Stamped with artist’s mark “AR” and “Hecho en Mexico” as well as possible eagle.Estimated creation date is 1949 - 1970. Metal has a goldish hue so I don’t think it’s sterling. However, I am not a jeweler and cannot verify any of the materials. Please purchase for beauty and history. CONDITION: Good VINTAGE condition. Standard dents and marks from wear. Working clasp. One earring is missing from one of the masks. Please review photos carefully and ask any questions prior to purchase.
