Thank you for submitting your item for appraisal. This appears to be a late 20th century chinese studio pottery bowl, stoneware of grey color, with applied ivy leafs and other flowers in relief, surrounding light cobalt blue glaze, marked with an impressed circular mark showing the character "gou" 苟, which has a couple of meanings in combination with other characters, but in this case would most likely represent a last name. The artist or workshop is not known.
The estimate is based on similar modern pottery offered or sold.
