by John Bierhorst, illustrated by Leo and Diane Dillon.
Published by Dial Books in 1970.
This is a beautifully illustrated book based on a Shawnee legend. I found it at a used bookstore the other day. The Dillons are some of my favorite illustrators.
Leo and Diane Dillon were a prolific husband-and-wife team. You can find a great blog of their artwork here.
