vintage Rosebleu Noritake Japan hand painted china dinner plates, old M mark

Lovely set of seven china plates, 1950s vintage, made in Japan. These are older Noritake pieces, each plate completely hand painted. These are dinner plates or possibly luncheon plates. They're 9 1/4" in diameter.

I don't believe this set was ever used, there's no scratching or utensil marks to the surface, no chips, cracks or staining. The fine inner line has wear from the plates being stacked together, but there's no sign of wear to the painted border.
