During the 1960's, Swank produced a collectible line of cufflinks called "Arts of the World". They imported designs from all over the world for these limited editions. They were priced at 4 times the price of their standard cufflinks. These are extremely hard to find and highly collectible.
They are made of carved sandalwood and set in gold tone "grass". They are in excellent condition and are signed with the Swank S logo on the back. I do not have their original box.
