Early set of Hull mixing bowls, banded, good pink and blue, yellow ware

Set of three early Hull pottery mixing bowls, yellow ware ribbed sides with banded pink and blue shades encircling the bowls. There are chips, cracks, crazing and scratches and wear, see photos. The bottom of each bowl says USA and a good number, D15 and D 16, I believe and I cannot read the other bowl. There is also marks from production in firing on the bottom. Perfect display pieces. They were used and well loved over the years.

Hand washed in mild soap and water.

Dimensions: small bowl diameter is 5-1/4", medium bowl diameter is 6-3/8", large bowl diameter is 7-1/8". The small bowl holds 2 cups, medium bowl holds 4 cups, large bowl holds 6 cups.
