The Caldecott Medal is awarded every year to the illustrator of the most distinguished American picture book for children.  It was founded in 1938 and is celebrating its 75th anniversary in 2013.  The Association for Library Service to Children, a division of the American Library Assocation, commissioned 2008 medalist Brian Selznick (The Invention of Hugo Cabret) to design this commemorative logo, which includes characters from some of the past winning books:
Make Way for Ducklings by Robert McCloskey (1942)
Madeline's Rescue by Ludwig Bemelmans (1954)
The Snowy Day by Ezra Jack Keats (1963)
Where the Wild Things Are by Maurice Sendak (1964)
Why Mosquitoes Buzz in People's Ears illustrated by Leo & Diane Dillon (1976)
Officer Buckle and Gloria by Peggy Rathmann (1996)
For these and more, visit the Caldecott Award section in the Kid Zone.  On your way there, stop by the special Caldecott display along the starred hallway.  Vote for your favorite illustrated book of 2012.  If your pick wins the 2013 Caldecott Medal (announced on Monday, January 28, 2013), your name will be entered into a drawing to win a copy of that book.
