Thank you for submitting your item for appraisal. This appears to be a last quarter 20th century chinese porcelain vase, transfer printed black outlines with additional hand painting and gloss gilding, bearing a rubber stamp at the underside " manufactured (?) for Maas Brothers Hand Decorated in Hong Kong". The estimate is based on similar items actually sold at auction. There is no measurement for the sentimental value you might attach to the item.
