Signed with initials "MM" which are attributed by many in the field to Maximiliano Mondragon, an early Taxco maestro who worked for Spratling and is considered among the most accomplished artists of his time. The "fertility" motif in this necklace is cut out of 980 silver sheet, deeply hand-chased and immaculately finished. The necklace measures an original 14 3/4" long which can be extended to a comfortable 17" with the sterling silver extension I am providing and it is 3/4" wide. It weighs a good 62.4 grams and is signed with maker's initials "MM" as well as "980 MEXICO STERLING" and Eagle 3 assay mark. Made in the 1950s-60s and in excellent vintage condition with warmly glowing patina, classically elegant and with no flaws noted.
