This shape is generally called an "Ewer". We would assume that this is a decorative piece only and wasn't really intended for use with liquids because of what appears to be a porous material. It has what is referred to as a "majolica" decoration (raised, not flat). If the piece is marked on the bottom by a famous maker, the value could be in the hundreds. Unmarked, we would expect to see a piece such as this go at auction for around $50.00-$100.00, without damage or repairs. Any repair of damage on a porcelain/plaster/china, etc., normally lowers the value by 1/2. Keep in mind, though, that auction values are normally 1/3 - 1/2 of retail. Hope this helps!
