Vintage Givenchy Paris New York 1976 Signed Necklace Signature Logo Snake Chain

This is a fabulous Vintage Givenchy Paris New York 1976 Signed Necklace. It has a Signature logo bar pendant set on a snake chain in silver tone metal. It measures at approximately 15.25" in total length with a spring ring closure. There is a bit of chipping in the coating on the top back edge (see pictures). I have seen others like this in gold tone, but not in silver, so this must be a rare piece. This is a pre-owned vintage item with minor wear, but still in good usable/wearable condition.
