An elegant and well-proportioned Art Deco silver-plated cocktail shaker, dating to circa 1930. The underside is clearly stamped Alexander Clark Co. Ltd., London, together with Wellner Plate, indicating manufacture by the renowned German silversmith Wellner, one of Europe's leading producers of high-quality silver-plated wares during the early twentieth century. The shaker displays the distinctive geometric styling of the Art Deco period, with its tapered body, stepped neck, integrated pouring spout, and finely modelled handle. It is a refined and functional design, equally suited to display or use. The piece remains in very good antique condition, retaining an attractive original patina with light surface wear commensurate with age and careful use. The silver plating presents well, with no significant dents or damage noted. A highly decorative and increasingly desirable example of early 20th-century barware, combining the quality of Wellner manufacture with the retail association of Alexander Clark Co. Ltd., London. An excellent addition to any collection of Art Deco silver plate, antique cocktail accessories, or decorative metalware.
