Libro Illeggibile by Bruno Munari
This "unreadable book" was designed by Munari for Corraini Books in 1984 He'd made this series since 1949, but this particular version was made just for Corraini. It's a work of art, that I find huge delight in sharing with others at the shop. Opening the book itself is like unwrapping a present, and then the "reader" can make their own "compositions" based on how each different section of pages unfolds. It's poetic, beautiful, fun and interactive. All the things we love about Munari himself.
