Vintage 925 sterling silver abstract wavy pendant on 925 snake chain necklace

Vintage sterling silver necklace. With asymmetric abstract wavy style pendant, it has a makers mark, as pictured. 16" chain 1.5" pendant (with bail). Both are stamped 925 sterling silver. The chain has a couple of small imperfections that are minor and almost not visible (one near the clasp and two shown with the green pencil). Still a very nice vintage piece in very good overall condition.
