Old ceramic vase signed

This pretty old vase 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... Elongated in shape, it is decorated with an irregular covering in blue, brown and cream. The decorations are formed by random drippings of the glaze. This vase is signed "rlle", I cannot identify the signature. It measures 18 cm in height X 7 cm in diameter at the neck. This vase is in perfect condition.
