Royal Doulton “Kay”, c1914
This lovely Art Deco design is from Royal Doulton c1914 from their “D” series of dinnerware.
Called “Kay” the design features a charming hand painted design in an Art Deco style, in blue overglaze on plain creamware//earthenware.
Pieces in this design don’t seem to have survived well if used, as the eathenware or “creamware” base is quite “soft”, and easily prone to chipping, crazing, cracking etc. However considering the year this was released, at the start of World War 1, industry would have been facing some very tough times.
You can work out the production dates from these “D” series wares from Doulton 1899 to 1964 on the link here
