The image displays a sculptural installation, identified as "Regał (Shelf)" by artist Oskar Zięta, located within the Zachęta National Gallery of Art in Warsaw, Poland. The central subject is a stack of four identical, trapezoidal metal units, each finished in a deep emerald green with a glossy sheen and equipped with two opposing U-shaped metal handles. These units are stacked in a descending, slightly offset vertical arrangement, with their internal structural elements appearing black. The installation is positioned on a flat, light grey floor, which reflects subtle highlights and receives prominent, elongated shadows cast by the structure, extending towards the lower right. The background consists of a plain, light taupe-colored wall. A focused artificial light source illuminates the upper left portion of the wall and highlights specific surfaces of the sculpture, creating strong contrasts and defined shadows. No individuals are present in the scene, and no discernible actions or interactions are depicted.
