Thank you for submitting your item for appraisal. This appears to be a chinese watercolour by 翁屏 Weng Ping, dated september 1973, with three red artist seal stamps. Very little is known about the artist. A few of his watercolours have been offered or sold at auction in China. The estimate is based on similar offered at auction. There is no measurement for the sentimental value you might attach to it.
