Caldecott Medal
The award is named for Randolph Caldecott, a nineteenth-century English illustrator. Rene Paul Chambellan designed the Medal in 1937. The obverse scene is derived from Randolph Caldecott's front cover illustration for "The Diverting History of John Gilpin" (Routledge, 1878, an edition of the 1782 poem by William Cowper), which depicts Gilpin astride a runaway horse. The reverse is based on "Four and twenty blackbirds baked in a pie", one of Caldecott's illustrations for the nursery rhyme "Sing a Song of Sixpence".
