A series of three books as written by the author Italo Calvino has been chosen for redesigning the book cover designs. In order to represent his whimsical and imaginative fables and fantasies, an optical illusion of the title is created on the front of each book with various line strokes. The line strokes form a key image on the each book in a abstract depiction. Windows on the cover reveal bright color to identify each book's uniqueness.
