For your consideration, please see this fantastic double-handled cream soup and under plate produced by Williams Sonoma Grand Cuisine. These particular bowls pre-date the newer "Essential White" pattern that was made in the 2000's, and as such, are not marked on the bottom of either the bowl or the plate. Out of all of the soup bowls and plates, which I have thoroughly cleaned and removed excess original sticker residue, I was able to find two with the original sticker in place, which is how I was able to properly identify the whole set (pictures are available).
The bowls measure 2 1/4" tall and 4 3/4" in diameter. The underplate (can also be used as a bread and butter plate) measures 6 1/2" in diameter. Please be sure to see all photos, as they are part of the description, and if you have any questions, don't hesitate to ask. There are multiple sets available. Will be packaged and shipped with care via USPS. Many thanks for looking and happy shopping!
