A yellow rectangular sign with rounded corners, featuring a black stick figure pushing a vertical door handle, is affixed to a transparent glass surface. Below the graphic, the text "ZATVARAJTE VRATA" (Close the Door) is displayed in black capital letters on a black background. The sign is centered within the frame. Through the glass, a modern interior hallway in a building located in Bar, Montenegro, is visible. The hallway is well-lit by recessed ceiling lights, which create reflections on the glass surface. To the left, a staircase with a silver-colored metal railing is partially visible. To the right, a wall is lined with numerous rows of light-colored, individual mailboxes or lockers. The background reveals a corridor leading to a further doorway, suggesting a common area within a residential or commercial building.
