In 1930 Ward's wood engravings were used to illustrate Alec Waugh's travel book "Hot Countries"; in 1936 an edition of Mary Shelley's "Frankenstein" was published with illustrations by Ward. Ward illustrated the 1942 children's book "The Little Red Lighthouse and the Great Gray Bridge", with text by Hildegarde Swift. His work on children's books also included his 1953 Caldecott Medal winning book "The Biggest Bear", "Nic of the Woods" from 1965 which he wrote and illustrated, and his work on Esther Forbes' "Johnny Tremain". He also produced a wordless story for children, "The Silver Pony", which is told entirely in black, white and shades of gray painted illustrations; it was published in 1973.
