"Plane/Figures IV" by Robert Mangold is a work on paper that employs graphite and colored pencil to explore the relationship between geometric abstraction and spatial representation. The piece exemplifies Mangold's systematic approach to investigating how two-dimensional planes can create the illusion of three-dimensional form through careful linear construction and subtle color modulation. This work reflects the artist's long-standing interest in the conceptual possibilities of drawing and the materiality of the picture plane itself.
