This pitcher appears to be a very rare Flow Blue styled pitcher in black. It has a very clear and well preserved Berlin Vase Pattern by J. Ridgway. This piece has a backstamp printed design with pattern name, potter, as well as a production number. Circa 1845 to 1850. There are no cracks, chips, crazing or hairlines. There appears to be a small amount of paint splatter and there is a small amount of discoloration on the inside bottom of the pitcher.
