A small green inchworm survives in a world of hungry birds by making himself useful. He can measure anything — a robin's tail, a flamingo's neck, a whole hummingbird. Then a nightingale threatens to eat him unless he can measure her song. Lionni's 1960 classic is as beautiful and brilliant as ever, its collage illustrations — a mix of cut and torn paper, colored pencil, and crayon — crisp and striking against open white space. This board book edition is an excellent choice for families reading with a younger and older sibling.
