Dear Bret,

Thank you for your request. The presented object is a mirror with the measurments of 3 x 5 feet. The mirror has a landscape form and is sourrounded by a waved form frame which, as well, is made out of mirror glass. This technique of frames out of mirror glass is very common in Venice. This piece was made in the 20th century.
An estimation would be between 80 to 150 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
