Smart-looking "No. 250 Coldseal" aluminum cocktail shaker by Kraftware, ca. 1946. The shape is very interesting, tapering from a narrow footed base to broader shoulders and a bell-shaped top. Raised rings add to the look. Bottom is marked "Kraftware." 12.5" tall. Nice condition. This shaker looks terrific when highly polished!! A wonderful addition to your collection, and relatively hard to find!.
