I would guess from the pictures that I remember that it was very Art Deco, from the 20’s, maybe the 30’s. I used to have it when I was 5 or 6, but it was old then. My Great Grandparents gave it to me, I think. I wore it out. It was my favorite. I think it was a thin book, like a Little Golden Book, don’t know publisher. I would love to know the title, author, and if any copies are available. The pictures are what are imprinted on my mind. If I see it, I will know it.
It is about 7 princesses that are awakened each night and secretly taken to another land, by boat, to meet their princes and (I think) dance all night. I don’t remember much more.
