vintage blue willow dishes - soup bowls & dinner plates, Royal china willow ware

Vintage blue willow dinner plates (about 9 3/4" in diameter) and soup or cereal bowls (about 6 1/2" in diameter). These aren't marked, but are probably USA pottery, Royal China?

These are good simple everyday dishes, not expensive porcelain - the stamped transfer does vary a little bit in color etc. from piece to piece. All eight pieces in this lot look very good without chips, cracks or staining, showing very little use.
