This is a sweet little vintage "country cottage" plate.
It was made about the 1930s by Carlton Ware.
It is from a series of designs made for the Australian market - and this one is the Buttercup plattern.
It has the maker's mark on the base as photographed.
It is in good vintage condition with no chips or cracks.
It looks great on a pine dresser or as a little serving dish on a rustic table.
At the longest point it measures about 7 1/2 inches.
Very fair price for such a pretty little piece of vintage Art Deco British ceramics
