This Zanesville Stoneware vase stands 3.5" high by 4.25" in diameter at the rim, and 2" at the base diameter. It has a small, yet shapely form with a flared rim and very subtle ribbing, shape 511.  We've never seen this form before, it has a very nice footprint. This vessel is glazed in a very rich matte green glaze.  It is marked with its shape number, and guaranteed to be a vintage Zanesville Stoneware form, c1940s. It is in original factory with the usual glaze nuances, and factory stilt pulls on the base edges as seen in the photos, but no apologies.
