These are quite unusual cufflinks of circular shape but with cuts-outs which create the head and wings of an eagle. Within this frame is the profile of a young gentleman with exuberant hair, high-necked collar and possible military uniform. We have now been informed by a knowledgeable Ruby Laner that this appears to be Napoleon's son, Napoleon II who became the Duke of Reichstadt. As his nickname was said to be L'Aiglon ("the Eaglet"), this would fit with the design. The actual cufflinks are attached by chains to a bar to secure them in position. The style is Art Nouveau but the gentleman’s profile and clothing are reminiscent of a much earlier century. There are no obvious maker’s mark and they are both in very good condition for age. These would be of interest to collectors of more unusual cufflinks. Diameter of circular component approximately 0.6 ins (1.5cm). Weight 6 grams.
