American Toby Jug Museum 

Crow creamer toby jug in a black colorway produced by Royal Tettau Porcelain Factory of Bavaria, Germany, circa 1910 using its Royal Bayreuth tradename. A crow is a bird of the genus Corvus, or more broadly a synonym for all of Corvus. Crows are generally black in color. The word "crow" is used as part of the common name of many species. This jug carries the MW Co. backstamp of US importer Mitchell, Woodbury & Co of Boston, Massachusetts.
