Lot is for a pair of pre-1940 vintage bar style cuff links manufactured by HICKOK in the USA--these are 5/8" square panel style bisected with a triple line cross design, two of the smaller panels (diagonally) being mirror-finished and the other two being matte finished with a engraved starburst pattern.  They are 1/2" in depth to the bar.  These are marked STERLING, dating them prior to 1940.  The pair of cufflinks weighs 6 grams.

These have a great mid-century modernist look to them.  A great pair to wear with your favorite formal wear!
