Richard Diebenkorn's *Woman Seated on Sofa* is a lithograph on wove paper that exemplifies his masterful approach to figurative work, capturing a solitary female figure in a moment of quiet repose. With his characteristic gestural lines and subtle tonal variations, Diebenkorn conveys both the physical presence of the subject and an atmosphere of introspective calm. The composition reflects his ability to balance representation with near-abstraction, drawing the viewer into the intimate, contemplative mood of the scene.
