12 Art Nouveau Tri Color Floral Vase Vintage. Although this vase appears to not be signed it is similar to a style used by the Daum Studios in Nancy, France. This is my untrained opinion so please view photos to make your own decision as to condition. Please zoom in on them. The vase measures about 12 inches tall x 3.75 inches at the top and about 3.75 inches at the base.
