Brilliantly innovative designer and artist Eric Carle has dramatized the story of nature’s commonest yet loveliest marvels, the metamorphosis of the caterpillar into a butterfly, in a picture book to delight as well as instruct the very youngest reader or listener. The brilliant illustrations, collages of specially prepared paper, and the cleverly die-cut pages show what the caterpillar ate on successive days, graphically introducing sets of up to ten objects and also the names of the days of the week in rotation, as well as telling the central story of the transformation of the caterpillar.
