My favorite fairy tale is one not widely known but it's in a most wonderful book (The Fairy Tale Book) that I've had since I was a kid. The illustrations are incredible, both black and white and color. It was published and copyrighted by Golden Press back in 1958. It has traditional stories from all over the world.
The fairy tale is "The Wild Swans" by Hans Christian Anderson. I like it because of the devotion and love siblings have for one another.
