Lovely soupière or tureen from French marque St Amand. The Nizon range with a centaur stamp on the base. 

Dark blue and white, it looks fabulous layered with other blue and white ironstone, please see other listings for a super slelction. 

This could be used for serving, I prefer them for display, flowering bulbs or packed with frothy hydrangea heads. 
The top is cracked and this is reflected in it being the price of an unlidded tureen, however on the lid does look super so I have included it for you, 

Measures 27 cm handle to handle.
