After 1910, a decorative style was established in Vienna with the interaction of colours and shapes as a main attribute. This style reached its peak during the First World War and was strongly inspired by the works of Dagobert Peche. An "Exglas" was a container for beverages that could not be put down, meaning that the content had to be emptied at any rate. Usually bride and groom were both offered an alcoholic beverage prior to the wedding to cope with their nervousness. It is signed at the top with "WW" and with a stamp on the bottom of the saucer.
