Leo Lionni changed the picture book landscape with beloved titles such as Frederick, Swimmy, and A Color of His Own. But those books are just a small window into his extensive career as a graphic designer, painter, and a master of fine art. Annie Lionni, Leo's granddaughter, and Leonard Marcus, a children's book historian, join us to talk about the life and art of Leo Lionni as shared in their new book "Leo Lionni: Storyteller, Artist, Designer."
