Vintage 1980's zip sweater by Hansen Knits in appleton

Vintage 1980's zip sweater by Hansen Knits in appleton. Has no size but I would estimate a small or medium based on measurements - please compare for yourself! Only flaw is some super mild pilling thats only noticeable up close. This is such a unique find! Hansen knits was a local part of zwicker knitting mills and is no longer open! measurements - pit to pit: 21 inches shoulder to bortom hem: 23 inches pit to wrist: 17.5 inches Comes from cat friendly and smoke free home!
