Originally published in 1964, children’s book illustrator Tomi Ungerer’s Underground Sketchbook lets loose a blast of social commentary, dadaesque observations, and existential angst, raging against avarice, unfettered consumerism, alienation, the mechanization of human experience, and the acquiescence to the worst instincts that fuel a modern economy – as timely now as it was then. This is as powerful a dose of visual ingenuity, moral outrage, and bemused disgust at the human comedy that you are ever likely to experience.
