What I have to offer for your viewing pleasure here is this beautiful pair of vintage Mid-Century Modern men's cufflinks by Hickok! They have beautiful dark round slabs of black abalone shell in gold toned settings, very Mid-Century & Art Deco streamlined. They are marked "HICKOCK U.S.A." inside the posts. They are in superb overall condition for their age. They measure 5/8" wide across the faces by 7/8" deep.
