Abstract Expressionism was an artistic movement in post-World War II America that featured large-scale abstract paintings using energetic, gestural brushwork. Jackson Pollock, a leading Abstract Expressionist, created the painting One: Number 31 by pouring and dripping commercial paint directly onto unprimed canvases laid on the floor, using an unusual technique that produced dynamic webs of lines. Pollock incorporated unusual found objects like coins and buttons into some of his works. The document encourages readers to analyze Pollock's paintings, experiment with their own abstract collages using cutouts from magazines, and present their creations to classmates.
