The children’s picture book “Funny Machines for George the Sheep: A Children’s Book Inspired by Leonardo da Vinci” (Prestel) is a clever introduction to Leonardo da Vinci and the painstaking art of invention. In this story by Géraldine Elschner, Leo perseveres to help a sheep that starts to shrink whenever it rains. Rémi Saillard’s illustrations convey the excitement of the creative process, which culminates in the fashioning of a device that is a cross between an umbrella and a parachute. Images of a self-propelled car, a paddleboat, and other da Vinci inventions provide a p.s. to the story and an invitation to activate one’s imagination.
