A striking French Art Deco silver plate cocktail or Martini shaker by Silversmith St. Hilaire, Paris. This generously sized Boston‑style shaker features a two‑part cylindrical form with a removable upper section and requires an external strainer (not included). Its clean geometric lines and elegant Deco silhouette highlight the refined craftsmanship of the period. The piece is marked on the underside with the official silversmith hallmarks of Maison Saint Hilaire, Paris.
