vintage Hearthside Japan Buffet Ware stoneware dinnerware, salad plates & mugs w/ wildflowers

1970s vintage Hearthside Japan Buffet Ware set of two 8 1/4" salad plates and small mugs (about 3 1/2" tall). One plate and cup are yellow primroses, one plate and cup are harebells (I think?). A pretty pattern, hard to find!

These look really good without scratching or staining, plates glossy without utensil marks, inside of mugs clean. BUT there's a little dulling or mineral deposits to the outside bottom of one cup, we didn't try to soak that off. Not new, but in very good condition overall.
