Vintage Sweater by Jantzen

Here is an awesome vintage sweater from the 1970s or early 80s by Jantzen Scotch Tumbler. Feels like wool or a blend, and made in the USA. Handsome tan butterscotch-y color, with four button front and nice collar shape. Medium weight, but warm and comfy. It's in amazing condition, and has years of life left. The tag says Medium, but here are the exact measurements, taken laying flat. (please refer to the last pic to see how I measure shirts)

Chest (armpit to armpit) 21"

Shoulder to end of sleeve (including cuff) 26"

Length 25"
