Gorgeous Vintage 70s Fur Jacket

Beautiful dark brown fur jacket, I'm not sure what type of fur it is. Long narrow strips of fur side by side give it a ribbed look. Zip front, high collar. It doesn't have a brand label, but my friend bought it when she was 17, which would have been '79 or '80. It is beautifully lined, and it is in amazing condition! Pockets are velvet lined, so warm! Armpit to armpit 18" Length from shoulder 23" Sleeve 24" There is a little bit of wear under the arms, you can see material between the strips of fur. But you don't see it unless you are looking for it, and it might have been made that way. Everywhere else, there is no separation between fur strips.
