1980s Vintage Geometric Graphic Turtleneck Pullover

Acrylic turtleneck pullover with a geometric pattern knit in primary colors. All edges are ribbed. When it's lying flat is measures 22" pit to pit, and it's 26" long. Sized a medium at the time, I'm calling it a small-medium now since it should be a very oversized fit. Condition is great. To maintain its texture, handwash and dry flat is best.
