The Toolbox was a close collaboration between Anne Rockwell and her late husband, Harlow Rockwell. Anne conceived of the book idea and wrote the text, and Harlow created the illustrations. He used handmade laid book paper instead of traditional watercolor paper, because he felt that this gave the color more transparency and luminosity.
Anne said, "I saw The Toolbox as lovingly rendered still lifes of common tools found in a toolbox, based upon my husband's powerful but sensitive and simple way of rendering everyday objects. The words were inspired by our son, a toddler at the time, and his awe of his father's tools."
Anne lives in Greenwich, Connecticut, and she is the critically acclaimed author of innumerable books for the very young.
