This is a most attractive mid-century Scandinavian design.
It dates to the 1960s and was made by Rorstrand and designed by Sigrid Richter (as annotated on the base).
I love this pattern - which is called Eden, and it features a large stylized sliced blue apple. The apple is surrounded by oodles of little abstract green leaves.
It is in very good vintage condition with no chips or cracks.
These plates are highly collectable and my price is a fair one for this most sought-after pattern.
