Here’s a great set of four vintage David Donahue men’s silk knot cuff links. They are round in solid red, royal blue, beige and yellow.  They come in a plastic rectangular container. Rarely used (purchased in 2001): knots are in great shape except one of the blue knots shows some wear, but still functional; case is a bit shopworn. Please see my other men's and women's clothing, shoes and accessories.
