This illustration is taken from the story “The Magic Hide and Seek” in Andrew Lang’s Pueblo Indian folk-stories from 1910. The image was drawn by George Wharton Edwards (1859-1950).
The image seems to be free of copyright but please give me some credit if you use it. Especially if you use the caption, which is of my own design.
