A vintage Avon silver necklace.  16" plus 3" extension. Widest area in front is approximately 2/3" and most narrow in the back is 1/2".  No markings inside.  This was owned by an Avon District Manager and may have been an appreciation gift to her.  Very nicely crafted, high polish, and no visible damage.   The necklace is heavy and substantial, and lays beautifully on your neckline.
