Thank you for submitting your item for appraisal. This appears to be C.Jeré wire wall sculpture of the 1970s, resembling a botanical garden glasshouse. Curtis Freiler and Jerry Fels founded the company artisan house in 1963 and chose the name C.Jeré for the wall decoration designed and produced in their workshop. The two founders sold their company in 1972, but the company is still producing similar wall decoration, since 2003 in China.
The estimate is based on similar wall decoration sold at auction. The more abstract pieces usually sell for higher prices.
