Silver Mounted Glass Liqueur Decanter Set c.1920

This is a fine and rare crystal glass decanter liquor set with solid silver collar and bases, circa 1920s. Of deep dark honey colour and hendecagon shape, the set is in the typical geometric style and design of Wiener Werkstätte (1903-1932) and the circle of Josef Hoffman and Koloman Moser. The silver is marked 800 and Ml, unidentified, possibly an Italian silver maker. The mark almost certainly refers to the silver maker only and not the glass decanter as a whole.
