Author and artist Andrew Glass illustrates his own stories, as well as those of other authors, and has been commended for his versatile approach to children's books. Art is so much a part of Glass's life that the first book he wrote and illustrated, Jackson Makes His Move, features a raccoon artist, rendered by Glass in pencil and watercolor. When Jackson realizes that he is no longer inspired by the country around him, and when he tires of his realistic paintings, he heads for the busy, chaotic city. There, instead of painting what he sees, he paints what he feels, and the resulting works are large and abstract. According to Kenneth Marantz of School Library Journal, Glass's illustrations help young readers "come to grips with some of the rationale of such movements as Abstract Expressionism." Since Jackson Makes His Move, Glass has gone on to write and illustrate such books as Folks Call Me Appleseed John, Mountain Men: True Grit and Tall Tales, and The Wondrous Whirligig: The Wright Brothers' First Flying Machine, often drawing on U.S. history for inspiration.
