Vintage Devon Wintuk Yarn Turtleneck Sweater‎

This vintage sweater by Devon still has a tag attached. It is made from Wintuk Yarn, something that apparently was used a lot in advertising when companies were using it as it was a new superior acrylic. I am guessing this sweater is 60s or 70s. I’m not entirely sure. It is in great shape. Has a zipper closure in the back and bright vibrant colors. No size tag though. Guessing small-medium 18” armpit to armpit 21.5” shoulder to hem
