Working together as children's book illustrators, they were one of the most compelling artistic teams I've ever seen in children's books. In fact one of the most compelling illustrators, period, whether a team or solo.
Their work is unique, distinctly their own, immediately recognizable. Their book of Greek myths was one of my earliest introductions to their work.
They were especially interested in folklore and myth.
Norwegian tales of trolls, gods, and goddesses filled many of their books.
Later, after they had emigrated to the United States, they turned their attention to American folklore and American heroic figures, like Pocahontas and Ben Franklin.
Their work is sturdy and full of vitality; it feels very physical.
Yet at the same time it is delicate and poetic, full of dream-like images and imaginative wanderings.Indulge yourself---look up some of the books created by this spectacular pair, and take flight!
