offers readers of all ages a seemingly endless series of stylized variations on the human face, each of which is a “double” that can be viewed without a top or a bottom, without a start or an end. By simply turning the book upside down, the reader/viewer causes each face to alter its expression in a variety of funny, unexpected and entirely delightful ways. Artist Gianpaolo Pagni infuses his gallery of characters with plenty of graphic snap and ingeniously invertable patterning.
