The view from above shows how the delicate cup is beautifully shaped to reflect the saucer.
The hande is a classic angular, stepped Art Deco shape.
As the backstamp indicates, this pattern was manufactured by CWS - the Co-operative Wholesale Society which would suggest this pattern was made for everyday usage for sale through Co-op department stores. Despite my research, I have not been able to find anything much more about this pattern.
