Here is a pair of extremely elegant double-faced cufflinks in the Art Deco style. The central panels have an abstract guilloche pattern under the white enamel. The sides are plain black. I believe these are from Norway, and I have a similar pair by David-Andersen, but these bear a maker's mark which I cannot identify.
Condition: Excellent, no visible damage
