vintage blue willow china cups & saucers, plates - willowware tea set dishes for 12

Nice large collection of vintage blue willow teacups and saucers and cake / dessert plates for 12. These are lovely pieces for entertaining, tea parties, weddings...

The plates are 6" in diameter, not marked with a maker. The cups are marked only USA (Royal China?), the saucers are not marked. The stamped transfer does vary a little bit in color etc. from piece to piece.

The entire lot looks very good without chips, cracks or staining, showing very little use.
