Ceramic salad bowl bowl signed

This beautiful old bowl is made of flamed stoneware. It dates from the 1920s and is signed under the base. In the style of denbac, from the beginning of the 20th century, it could be a production from alsace... Round in shape, it is a salad bowl or bowl decorated with an irregular cover in blue, green gray and cream. The decorations are formed by random drippings of the glaze. This cup is signed "rlle" or "dille", I cannot identify the signature. In very good condition, it measures 21 cm X 24 cm X 9 cm in height.
