1970's Vintage Hand Knit Boat Neck Sweater with Motorcycle detail

Kinda the raddest sweater. Mens Size Large hand knit 70's sweater. Purple lol. See images for length measurements. Great for a guy 6ft or over. I wear a womens size 6 (medium top) and am 5'11 and this is pretty big on me (in case you're a gal and curious about fit for you). It's vintage so there is some normal wear and tear. I believe it's a cotton/acrylic blend. Not wool. Soft. ** one button missing (5th from top)
