Polychrome enamelled stoneware vase by Dubois - Belgium - art deco

Large ansé vase in bouffioulx sandstone (belgium) signed under the dubois base named after the dubois pottery which has several generations of potters. Work from the 1940s. Emaux green of nuanced gray and beige with blue reflections, applied on a decoration in relief at the base perfect condition. Photos are part of the description. I'm not a fan of sandstone but the slim shape enhanced by this little fafelu side of geometry makes me think of a lamp foot!.
