Dear Lyons,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a wall decoration made out of glass with an iron or steel mounting with the measurements of 22 inches radius. This piece is a typical product of the glass production of Murano in Venice and was made by AD Murano Glass.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 700 to 1.500 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
Georg
