A joyful romp through art, imagination, and the life of Randolph Caldecott—the artist who changed picture books forever! Tomfoolery! bursts with energy as it tells the story of a young illustrator who refused to sit still. In a world where children’s books were stiff and serious, Caldecott’s pages danced with life—rabbits leapt, wind swirled, and laughter filled the margins. His playful spirit reshaped the very idea of what a picture book could be and inspired the creation of the prestigious Caldecott Medal that bears his name. With Michelle Markel’s lively storytelling and Barbara McClintock’s wonderfully detailed illustrations, this award-winning biography captures the humor, movement, and joy that define both Caldecott’s work and the childhood imagination itself.
