I recently bought this large (20cms) and very heavy (2.2kg) trailed & faceted vase at a jumble sale. The seller claimed it was Mandruzzato, but I'm not entirely convinced by his attribution. In particular, the very deep pontil (3cms deep -see image) is not a characteristic usually associated with Mandruzatto. However, I have seen a very similar style attributed to Pavel Havla for Exbor. I'm certain that, among our Members, there are many who are infinitely more knowledgeable than myself, and can speak with far more authority than either the seller or myself. Many thanks for your help. Larry.
