With his sly sense of humor and his expressive line drawings, Shel Silverstein remains one of the all-time greats of children's literature, not least because he produced books that dare readers 4 to 8 to interpret them their own way.

Also from 1964, A Giraffe and a Half finds Silverstein at his most madcap, his surreal drawings paired with zany rhymes. Both books come in a heavy cardboard slipcase with a black ribbon tie
