I'm considering purchasing a very large, ocean blue Cenedese battuto vase from a dealer who believes it's a priceless masterpiece (slight exaggeration). It's signed with inscribed "Cenedese" on bottom, and is in a simple conical shape, measuring about 14 inches tall. The texture has a heavily chiseled look with white scratches on surface. Overall it's pretty stunning. I cannot for the life of me find a reference to anything like it in any books or on the net, and my hunch is that it's not vintage but rather 1980s, 1990s or 2000s. Does anyone know when this line was produced and its approximate cost when new? And who designed it?
