Meet Randolph Caldecott, the artist who revolutionized picture book illustration and for whom the prestigious Caldecott medal is named! From acclaimed picture book creators Michelle Markel and Barbara McClintock comes a lively, humorous, and energetically informative biography that celebrates the spirit of storytelling in art. Quick! If you don't move fast, you'll miss him-there he goes-Randolph Caldecott, future famous illustrator. His sketchbook is full of hurly-burly: wild weather, frisky animals, and people so sprightly they can barely hold onto the pages. But in the 1850s, there were no children's books like that. Not yet.
