This is a rare Royal Bayreuth tomato and leaf mustard bowl. The unmarked piece stands 3 1/4" and has a green handle.
The Royal Bayreuth factory was founded in Tettau, Bavaria, in 1794. It has continued to modern times. The marks have changed through the years. A stylized crest, the name Royal Bayreuth, and the word Bavaria appear in slightly different forms from 1870 to about 1919.
