I couldn't resist this Barbini vase. I like the combination of incalmo and sommerso effects. I have not seen anything quite like it before, and cannot find comparable pieces in any of my reference books or on the net. I'm assuming it is circa 1980s or 1970s, but (obviously) hoping it could be older. Can anybody help me to date the piece, or tell me more about it, such as designer or name for the series?
