First Edition. 2 by 2 inches, silverplate shell with celluloid wheel. A rare silverplate cocktail recipe disk by Napier whose silver designs from the first half of the 20th century are in museum collections including the Brooklyn Museum, Newark Museum and a substantial collection at the Dallas Museum of Art. The silverplate case holds a celluloid dial that can be rotated to show printed recipes for twenty classic cocktails. The back side is marked 'Napier Pat. Pend.' Scarce. Very Good but for silverplate mostly rubbed down to copper underneath.
