the old man's head

This ornament has been in the family for years. We call it the old man's head. but i did not know much about it so today i tried to do some research.
i found out it is a tobacco jar made by B. Bloch & Co
In 1871, Bernhard Bloch established a pottery in Eichwald,(now Dubí in the Czech Republic)
it was renamed to Eichwald Porcelain and Stove Factory Bloch & Co in 1920 and During the Second World War, the factory was confiscated by the Nazis and sold to the company Dr. H. Wider & Co.

i don't know at what point in B.Block & Co's history it was made or if it is the likeness of anyone in particular.

if you know let me know,
here are some other photos i found online of it
