Inspired by, but NOT intended to be an accurate representation of, the Inuit folktale The Fox Woman. (This is the third and final illustration in my series inspired by folklore about wild canid spirits that shapeshift into human form.)
In the original tale, the fox sheds her skin to take human form, and resumes her fox skin to leave when her human husband complains about her.
Another retelling of this Inuit tale is available in World Folklore for Storytellers: Tales of Wonder, Wisdom, Fools, and Heroes.
