To understand the book "In the Dark Night", we should start by saying that in the beginning it was the unreadable book: a kind of book without text, whose abstract images are transformed as you turn the pages. According to Munari, these books were meant to experiment with all visual communication options and printing techniques that did not involve words.

This is how the book "Na Noite Escura" (In the Dark Night) emerges. An object that reconfigures the relationship with the reader by combining the visual side with the challenge proposed by the materials themselves, which also become agents of narration. Nothing is accessory in this book, all visual aspects and materials interconnect to build a single and indivisible structure, full of meaning. A true masterpiece from the hands of one of the most influential designers of the 20th century.
