This shard was found on Eastport, Maine shores, as are all others unless otherwise noted.
"This ‘Imperial Crown China, Austria' backstamp was the pottery mark of a decorator and importer as distinct from a manufacturer. It was the mark of Bawo and Dotter who basically decorated blanks at their studio in Fischern which was then in a region known as Bohemia now called Rybáře, Carlsbad in the Czech Republic. However, their main office was in New York and they also had a decorating plant in Limoges. They were founded c.1883 and went on until c.1914. These Imperial Crown Austria porcelain wares are highly collectible and one plate can fetch on the region of $20 USD."
"Germanic makers using the name "Crown Imperial" or similar are actually paying homage to world renowned original Austrian maker Royal Vienna (the one true Imperial company of Europe), one of the original hard-paste European innovators back in the 18th Century."
