Tall Stoneware Vase with Purple, Blue and Gray Glazes

A handmade stoneware flower vase featuring a rounded and ribbed (but slightly askew at the top) body glazed in purples, grays and blues leading up to a rim that is pinched on either side of the opening (see pic).  The vase measures 5 1/4" long, 2 1/2" wide and 9 3/4" tall.  The bottom is signed and the condition is good.
