The Hazel Atlas Glass Company made several tea sets in the 40′s and 50′s. The earliest set was the Little Hostess, followed by the Sierra, and finally the New Century set, which is the one I found.

Unfortunately the New Century set was not designed with a teapot, but it does have the cute creamer and sugar bowl (which apparently are always pink). The original Little Hostess colors were pastel like mine, but the Sierra sets came in several different color schemes.
These little dishes were stacked with the regular cups and saucers at the Goodwill several years ago. It’s a complete 14-piece set, plus several extra pieces. At the time I purchased these dishes I had no idea who made them — I just loved the pastel colors and the milky glass — and they were only 50 cents each.
