This book, published in Spanish in 1968, is translated to English for the first time. A blend of lecture notes, class materials and letters invites designers and thinkers to reconsider how visual communication operates, spanning everything from typography to optical illusions. Munari’s clear voice, steeped in curiousity, makes connections between art, architecture, design and daily life, urging readers to see the world with fresh tools and new awareness. The annotations by scholar Jeffrey Schnapp deepen the experience, making this historic 1968 text feel thoroughly modern and relevant for today,
