An interior scene in Plovdiv, Bulgaria, displays a light-colored wall adorned with an arrangement of twelve framed prints. The prints are primarily reproductions of scientific and artistic sketches, rendered in blue or light blue ink on white backgrounds, consistent with the style of Leonardo da Vinci's notebooks. Subjects include the Vitruvian Man, studies of horses, bats, botanical illustrations, and designs for mechanical devices such as a bicycle, flying machines (including an aerial screw), and other contraptions. Many prints incorporate handwritten text and mathematical notations. The frames are predominantly dark brown, with two frames (one containing the Vitruvian Man and another titled "Leonardo da Vinci" with a bicycle) being a lighter, possibly gold, metallic color. The prints are arranged in a staggered pattern across three rows and four columns, covering a significant portion of the wall. In the lower foreground, the top section of a light-colored upholstered furniture piece, likely a sofa or armchair, is visible. It features a beige or off-white fabric, possibly leather, with subtle embossed detailing. A small portion of a patterned cushion or throw rests on the left side of the furniture. A thin white molding separates the wall from a light-colored ceiling at the top of the image. No individuals are present in the scene.
