Caldecott Medal
Illustrator Gail E. Haley has won both the Caldecott and the Kate Greenaway Medal, the comparable British award for children's book illustration (not restricted to picture books). She won the Caldecott for "A Story a Story" (Atheneum Books, 1970) and the Greenaway for "The Post Office Cat" (The Bodley Head, 1976). Haley and her second husband lived in England from 1973 to 1980. From about 2000 the British award is open to all illustrators.
