A human left hand, palm open and fingers extended, occupies the foreground, heavily coated in a fine, light-colored particulate substance. The background consists of a light brown wooden plank floor, also dusted. Adjacent to the wooden floor, an area of exposed concrete subfloor displays irregular textures, grooves, and remnants of removed material, likely adhesive or grout, with embedded linear dark grey elements. The scene depicts an interior environment consistent with a construction or renovation site. The specific location in Erba, Italy, is not discernible from the image.
