This is an edition work by Yoshishige Saito composed of Bopan K board, synthetic resin, and aluminum plate (ED.50), created in 1971 and bearing a plate signature.

The composition presents a dark aluminum surface layered with smooth material, into which delicate engraved lines are introduced. A softly contoured form emerges at the center of the composition, while sharp linear marks appear within the shape. Within the restrained monochromatic surface, subtle reflections of light interact with the material texture, creating a quiet yet tense visual presence.

During the 1970s, Yoshishige Saito produced numerous relief-like works using industrial materials such as metal plates and synthetic resins. These works explored the boundary between painting and sculpture, emphasizing both the physical presence of the material and the spatial qualities of the surface.

Saito is regarded as a major figure in postwar Japanese abstraction. Through works such as this, he developed a distinctive visual language that merges material structure with spatial perception, positioning his practice between two-dimensional painting and three-dimensional form.
