The Museum of Modern Art purchased Pollock's 1943 The She Wolf a few weeks after it was first exhibited. His huge 1943-44 Mural, painted for Peggy Guggenheim's townhouse, was included in MoMA's 1947 exhibition Large Scale Modern Paintings, along with work by Picasso, Matisse, Beckmann, and Siqueiros. The Museum bought Number 1A, 1948, a classic "drip" painting in 1950, and later acquired One: Number 31, 1950, one of three monumental canvases from that year. In 1980, a generous gift from Pollock's widow, Lee Krasner, helped make possible the acquisition of another seven paintings spanning the artist's career.
