"Superb Art Nouveau Vase In Earthenware Germany? Unique"
Superb vase probably German. It is signed and with a note below. It is surely an academic and unique work. From the Brussels collection. There are two slight chips on the base, nothing serious. The piece is very powerful, never seen this type of ceramic. In short, an interesting piece.
