One late spring morning the American artist Jackson Pollock began work on the canvas that would ultimately come to be known as Number 1, 1950 ("Lavender Mist"). Award-winning authors Jan Greenberg and Sandra Jordan use this moment as the departure point for a unique picture book about a great painter and the way in which he worked. Their lyrical text, drawn from Pollock's own comments and those made by members of his immediate circle, is perfectly complemented by vibrant watercolors by Robert Andrew Parker that honor his spirit of the artist without imitating his paintings. A photographic reproduction of the finished painting, a short biography, a bibliography, and a detailed list of notes and sources that are fascinating reading in their own right make this an authoritative as well as beautiful book for readers of all ages. Action Jackson is a Sibert Honor Book, a "New York Times "Best Book of the Year, and a "Publishers Weekly" Best Book of the Year.
