I have completed the set of Gourmet casseroles, I believe. Does anybody know if they were made in any other colors? According the Pyrex Love, the bottom piece was a Winter 1961 promotional piece. It is delphite blue with white paint fired on with a gold leaf design. In the middle is an opal white casserole with black print, and on top is an opal piece with a butterscotch fired on paint and gold leaf design. All three are the 2.5 quart size, and I love the way they look stacked on top of each other in this picture!
