Here is a lovely pair of double sided Art Deco cufflinks. They were made by a company called Foster & Bailey, which was an American silversmith that operated from1878 until 1898 out of Providence, Rhode Island. They continued to operate in 1898 to 1951 under the name Theodore W. Foster and Bros. Guilloche enamel is a decorative technique in which a very precise, intricate and repetitive pattern is engraved into the material. In this case, white enamel was used to melt over the top of the engraving. A smooth ring of blue enamel frames these cufflinks. A great set to add to your collection.
