Clark Art Deco Engraved Gold Top Cufflinks. Clark engine turned gold top cufflinks are exquisite and resemble their solid gold counterparts. These links are made by the W. G. Clark and Company and are marked on the connector with their logo. The tops are yellow gold with a lovely engraved engine turned designed popular in the 1920s. The yellow gold centers are rimmed with a lighter shade of gold rim which also has an engraved design. As with most Art Deco jewelry, they are small in size and measure 9/16 inch in diameter and are in very good condition.
