With a sprightly text and his most vibrantly colored collage illustrations to date, Carle tells the story of Walter, the best baker in the Duchy who, under creative pressure, invents the pretzel. Based on a German folktale passed down to Carle by his grandmother, this delightful story illustrates how necessity and accidents are the mother and father of invention.
