This is an older bracelet dating from the 1920's to the mid 1940's with three onyx warrior masks channel set in silver panels.  There are four more panels of "grapes" also set on panels.  The push clasp is marked with the initials "P.L." in script and "Mexico" also in script.  Below that is the word "Sterling" in a plain san serif type.  This bracelet is in good vintage condition with some dings to the grapes and minor chipping to two of the warrior's noses.  There is a good patina and the clasp works well with a crisp click.  Weighs 53 grams and measures 6 3/8" without the clasp.
