These silver plated cocktail shakers were made by the Napier Co. (Meriden, CT) in the 1930's. The first one is from 1932 and was the first cocktail shaker manufactured by Napier. It is the Tells-You-How-Mixer (just turn the body and the ingredients for all your favorite drinks appear in the windows). The middle one is the rare pengiun shaker from 1936 by Emil A. Schuelke. His beak opens when you pour. The third one is a sleek conical design from 1934, also by Schuelke.
