From my research on this mayo set, I have discovered that it was made around 1940 and the maker is unknown. It is quite elegant with a grey cut rose and leaf etching on both pieces. Both pieces have a ground bottom rim. The plate measures 7-1/2" across; the divided bowl measures 5-3/8" wide and 2-1/8" tall. Both pieces have a teenie bubble in the glass along the outer rim. They are in excellent condition with no chips or cracks other than a pin head sized nip on the top rim of the bowl, not seen unless closely examined (that is a bubble in the glass that you see in the photos). Small amount of light surface scratches in the center of the plate. Glass is clean and clear with no cloudiness. Nice quality glass on this set!
