*Mary Cassatt: After Impressionism*, marking the centennial of her death, gathers more than 75 paintings, pastels, prints and ephemera from the late 1880s to the early 1900s, after the last Impressionist group show. Mothers and children, complex color prints such as *The Letter* and material on her lost mural for Chicago’s 1893 World’s Fair trace her turn toward bolder, modern work.
