One of my favorite sets that I have been lucky to be in the possession of! The wonderful thing about this set, is that not only is it a full set, but it's in great condition!
This is called a Little Hostess set, made by Hazel Atlas in the 50s or 60s. It was made for little kids to use, which is why finding a complete set is difficult, as kids generally broke a lot. This is in such good condition I would almost say it's never been used. But, I won't say that because it's not in a sealed box. Either way, it's a beautiful set. Fired on pastel paint onto milk glass, which you can see on the bottom of the plates and cups.
I really do love this set! It's for sale on my etsy site though.
