Description

I don't know where to start to find more information and value for the vase. It is heavy and thick and made in Italy, it has a very beautiful form and style. It reminds me of Deco or Nouveau. The bottom of the vase says 12 and Italy. I hope by the pictures below you can see exactly what this piece looks like.

Please let me know if you think you can estimate a value for this piece!!! Thank you!
