These came in various colors (light blue and yellow being the most common; red (both a dark red and a lighter blush) and white being harder to find; I have heard of purple but I have never seen it). Your Menschik-Goldman mark is interesting. I am not questioning the authenticity of your set, but usually they are marked more clean (yours looks like the ink stamper was drunk LOL). They marked their items with the Menschik-Goldman, Inc. both with Japan and without. They also abbreviated it to M-G, Inc. Plastic sets will denote Hong Kong. I have only ever seen the stacking measuring cups with wet feet, yours are dry. Again, just a note. You can sometimes find them with a green M-G sticker. My wife and I have found stacking measuring cups, salt and pepper shakers, a honey pot, and a covered sugar bowl. Menschik-Goldman was the exporter; these were sold by Woolworth and several other department stores from the early 1950s (possibly as early as 1949) through the decade.
