Chaps Sweater size Large 16/18

Vintage Chaps Sweater size Large 16/18 very nice sweater only disclaimer is sweater has some black marks in 3 places on sleeve, side and back of sweater as shown in pictures. Spots might come out with extra attention on those spots. Runs a little small to me seem more fit for a young adult size. Might be how this style is this is a older style.
