Chwast has illustrated and/or written some 40 children’s books in the course of his career. His poster promotes Harriet Ziefert’s Moonride; Chwast provided illustrations for this story of a boy and his night ride through the city in his characteristically bold, saturated colors, and with the humor and attention to detail that children seem to love. “Children respond to the kind of artwork I do,” Chwast wrote in his 1985 monograph The Left-Handed Designer. “What’s odd is that my children’s illustrations are sometimes considered too sophisticated. I don’t understand that at all unless my work is not cute enough for children. Ironically, those reactions go against my innocent, head-on style. You see, there’s nothing beyond what I’m doing. It’s all laid out. There’s no symbolism, no mystery.”
