I have tried my best to identify the maker of this vintage bowl set.  I bought from an estate sale, where they were shoved back into a corner in a cupboard, dusty as heck.  Cleaned up nicely, but I haven't been able to find the maker.  In the popular primary colors used in the 1930's and 40's, the inside is clear with the colored coating.  Each measures approximately 2 1/2" tall and 5 1/4" in diameter, and hold about 20 oz.
