Mid century mod vintage Portmeirion pottery plates, made in England. This is a set of six plates about 8 3/4" in diameter, a coffee brown color. The border is concentric circles or dots, Jupiter pattern from iconic 60s designer Susan Williams Ellis.
These plates are used, showing glaze crazing and some visible utensil marks. It's a design that's almost impossible to find these days, so I grabbed these when I found them, in spite of their flaws!
