51 works by artists from around the world: from Marcel Duchamp to Ai Weiwei, provide examples from all directions of modern art, allowing children to engage with the question of whether and why something is art. The craziest things can be art: a sawed-off house, a blue piece of tape, poems on stones, a felt blanket and a coyote, snow made of paper scraps, or wrapped islands. The book showcases fifty-one works from the last 95 years by artists from around the globe, including Joseph Beuys, Christo and Jeanne-Claude, Fischli & Weiss, John Cage, and Ai Weiwei. Each piece is backed by a unique idea, an experiment, a crazy story, an adventure. They stimulate the imagination and open our eyes to things we had not noticed before. The examples from all art forms give children the opportunity to express themselves creatively.
