Oxford stoneware, vintage blue glaze pottery kitchen mixing bowl

Vintage pottery mixing bowl with sky blye glaze, measures 7" in diameter across the rim x 4" deep. The underside of the bowl is marked Oxford Stoneware, this is 1930s, 40s, or 50s USA pottery (not English at all!).

There's a tiny glaze chip to the rim, but the bowl looks very nice overall, no cracks, crazing, or discoloration.
