Vintage JC Penney The Fox wool blend gray/white crewneck sweater, men's size M

Vintage men's wool blend crewneck sweater, size M. No material tag, but other sweaters that look similar online are showing 70% wool, 15% acrylic, 15% polyester. Feels soft to the touch, but you can tell there's wool. Do your own research regarding material prior to purchase. Measurements are listed in pictures, no flaws noted. This is very well made - classically 80s preppy! Recently machine washed on cold, air dried on a drying rack. It came out perfectly, so easy care wool.
