Hi Pup,

Thank you for contacting Mearto with your appraisal inquiry.
The values Mearto provides are fair-market, for auction purposes. While Zanetti's works retail for quite a bit of money, his pieces have not yet developed enough of a following at auction to bring similarly high prices. While I might expect to have to pay well over $1,000 for this in a gallery, at auction it would be unlikely to sell for more than $500.
Based on the photos and information provided, and subject to examination, this is:

An Oscar Zanetti handblown figural sculpture
made in Murano, Italy, late 20th/early 21st Century
Two abstracted figures facing each other, on a black plinth signed Zanetti Oscar
20 inches high 11 inches wide, 8 inches deep
CONDITION: not examined in person but appears to be in excellent condition
PROVENANCE: acquired from an Italian gallery
$300-500*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
