Vintage Duke Sweatshirt with Signature Pullover Crewneck Medium

Vintage Duke Sweatshirt with Signature Pullover Crewneck. Size medium. The tag is The Cotton Exchange. 100% cotton. Does have what appears to be a signature on one of the arms.

Item has been laundered but there are spots throughout the sweatshirt, as shown in photos.
