Structures of Difference brings together works of art made during the past 50 years, including figurative and abstract painting, photography, and sculpture. They are linked by the idea of difference, which plays an important role in both the creation and perception of these works. The uses of difference as a structural device, as a thematic focus, and as a perceptual effect are explored through groupings of works that cross boundaries of period, media, and style, revealing connections between late 20th-century innovations and more recent artistic projects.
