A great gift for the Vintage Gentleman! Beautiful 1960s Vintage Mid-Century Modern Mad Men Era Silver Tone Cufflinks set. This large, flashy cufflink set features large iridescent dichroic glass seashells or clam shells in shiny silver tone metal settings. The cufflinks have bullet back closures; a torpedo, or bullet shaped, capsule that is suspended between two posts. The bullet can be flipped on its axis to manipulate it through the button holes in the cuff, and then flipped to secure the cufflink on the shirt. The cufflinks are marked "HICKOK" on the posts. They are quite well made and in excellent unused or barely used condition! The cufflinks are a large size, measuring 13/16" across. Our vintage men's cufflink sets include a paper gift box with cotton lining and make a great gift for the vintage gentleman!
