Dear Natalie,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a stained glass art piece with the measurements of 13 x 7 inches. This is a reproduction of a draft for the design of a window by Frank Lloyd Wright made by the Frank Lloyd Wright Foundation in the late 20th century.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 50 to 100 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
