Thank you for submitting your item for appraisal. This appears to be a 20th century japanese four panel screen, signed 園柏 (?). These capriccio landscape screens depicting an ideal landscape with rivers, mountains, pavillions and coastlines are quite common and were produced for home decor. The estimate is based on similar offered or sold at auction. "Asking prices" in the trade can be higher and vary. There is no measurement for the sentimental value you might attach to it.
