The shape of this set is probably #528 as shown on the upper left in this catalog of milk glass cream & sugar sets: Imperial 1955 Catalog page.
IG milk glass patterns were usually issued in Doeskin too. Documentation on this particular rose pattern has not been found.
The lower image of the sugar has been darkened to bring out the rose pattern; the image above it is the true color.
The pieces are very nice quality, and the IG mark is on the bottom of both. Even the inside of the glass has a texture to it, although it is much smoother than the outside.
The sugar measures 5 1/8" from handle tip to handle tip, 3 3/8" across the bowl from front to back and 2 1/2" to the rim of the bowl (at the center).
