This 1950s metal cake saver or keeper was made by Decoware. The top of the cover and the base plate are coppertone plated tin. The sides have a black and coppertone flower basket decoration on three sides. It measures 11-3/4" diameter at the bottom by about 5-1/2 inches high. The keeper is very clean, but does have a ding on the upper rim (second picture) and some minor marks to the finish from storage and use.
