Eugenio Pattarino (I think), Otella Rosa - Theatrical Vase

We would like to sell this item but would prefer learning about it before it is listed for any type of auction.  The vase is very old and in mint condition (no cracks or chips).  Any imformation you can provide would be greatly appreciated.  We don't know if this a piece by Eugenio Pattarino or Otella Rosa (maybe they are the same person).
