A valued collectible by a German porcelain factory from the 1920's-1930's. Extremely rare, I have only found them overseas and you would have to have it shipped to the states. Here, I ship only within the USA. Vollmer Stumpen is 5" x 5" and was made by the Nieder-Salzbrunn porcelain factory, started by Julius and Ernst Prause in 1891. Named after the already deceased Franz Prause, near a trio of little towns, now know as Sczawienko. The porcelain factory was converted to manufacture everyday, inexpensive kitchen and table wear, like ashtrays in 1921. They could not maintain operations during the world economic crisis after the war and it had to be closed in 1933. This particular piece has some factory imperfections that I have pictured here.
