This image depicts the interior of a classroom located in Dupnitsa, Bulgaria. The central focus is a large wall mural spanning the majority of one wall, featuring three distinct male figures rendered in a stylized, illustrative manner with a limited palette of browns, beiges, and dark outlines. The leftmost figure is a man with dark hair and a prominent mustache, appearing to rest his chin on his right hand. The middle figure possesses light-colored hair and a large, ornate mustache, looking slightly to his left. The rightmost figure is a younger man with dark, disheveled hair and a full, thick beard and mustache, gazing directly forward. All three figures wear formal attire. The room features light-colored walls, a light wooden floor, and a white ceiling equipped with two parallel fluorescent light fixtures emitting cool white light. On the right side of the room, a window is visible, covered by vertical red blinds through which sunlight or an external light source casts distinct linear patterns of light and shadow onto the floor and adjacent wall. Multiple rows of empty student desks, each with an integrated gray chair and a light-colored wooden top on a gray metal frame, are arranged throughout the classroom. The overall lighting within the room has a pervasive pinkish-red cast, notably affecting the wall colors and the general ambiance.
