This is a pair of ornately engraved napkin rings, in sterling silver. Each ring has a pair of crossed tennis rackets, with a ball centered on the head of the racket. The rings themselves have decorative and elaborate cutouts.
Napkin rings are thought to have originated in 19th-century France, where sterling silver serving implements of every imaginable shape and purpose were the rule on the fashionable dining tables of the well-to-do. The napkin rings were often figural, depicting all sorts of animals, from dogs to horses, or sporting themed. By the end of the 19th century, companies like Tiffany & Co. in New York and Liberty in London were producing Art Nouveau and Arts & Crafts napkin rings.
Each ring measures approximately 2 1/4" H x 2 3/4" W x 2 3/4" D
