Large bowl 12 inch diameter, 5.75 inches high. Smaller bowl 9.25 inch diameter, almost 4.25 inches high. These bowls appear to be from the earlier half of the 20th C. I do not know the maker. Should be from the same maker with identical lighter blue glaze and ribbing and blue glaze swirl on both bases. They are both in reasonably good condition. Each bowl has a light crack from top edge going about halfway down inside (shown in closeup photos). Other minor signs of age and use, and surface irregularities from original production. The photos show a good view from all sides and angles for careful evaluation. Any questions please ask. Packed carefully, double boxed.
