Incredibly Rare Vintage Hermes 100% silk wool deity black cardigan sweater

Incredibly Rare Vintage Hermes silk deity black cardigan sweater. Overall excellent condition considering it’s age (guessing 70’s or 80’s?). This was a gift from an ex so I don’t have all details but you can see the construction and quality. Mother of pearl buttons, interesting sleeve construction/tailoring. Laying flat total length is approximately 23.5 inches unstretched. Approx 18” across armpit to armpit.
