Beautiful 1960s Vintage Men's Cufflinks with Antique Car designs by CTO. A nice set marked "1/10-10K" which means that 1/10th of the weight of the cufflinks is 10 karat gold. They are also marked with a maker "CTO". The cufflinks have bullet back closures; a torpedo, or bullet shaped, capsule that is suspended between two posts. The bullet flips on its axis to manipulate it through the button holes in the cuff, and then flips to secure the cufflink on the shirt. These terrific cufflinks are a large size, with the faces measuring just 1-1/8" across. The cufflinks are quite well made. A fun men's accessory set in nice shape in original Turquoise Blue Leather-Look Presentation box with gold trim and cream colored velvet lining! A great gift for your favorite vintage gentleman!
