This standard lamp is depicted in the Wiener Werkstätte photo book (WW 97, vol. 9, p. 46-4). There is a sketch in the model book (32, metal 4, p. 1275) with a note: “O. Prutscher, 17.12.1909, für Herrenzimmer Böhler“ [for the Böhler study]. Only one of these was ever made and sold for the more than impressive price of 1,200 kronen. We would like to thank Frau Hermi Schedlmayer (author of an Otto Prutscher catalogue raisonné to be published soon) for the kind information.
