Vintage Statement Necklace: Premier Etage Paris Choker with Animals

This is a substantial couture necklace made of silver infinity links attached by gold links. Well crafted and detailed animals--squirrel, camel, bear, elephant, horse, frog, in two tones, dangle from the bottom row. It measures 16 1/2" long and has a toggle clasp. It is signed "Premier Etage Paris" on a small silver circle, and lettering on the back that I can't quite make out yet. There is also a gold round tag on the other side which reads: "Not returnable if this seal is removed" 0532/0537 on one side and on the other, Henri Bendel in script. The necklace itself weighs 9.6 ounces.  Never worn, in excellent condition, likely from the 80s.
