An interior corner in a building in Sedlartsi, Bulgaria, is depicted under artificial lighting. The left and right walls are constructed of exposed light brown/orange brickwork, partially covered by a roughly textured, light grey plaster. Exposed wooden ceiling beams are visible in the upper left corner, where the plaster meets the unrendered brick. Centered on the plastered wall is a piece of graffiti featuring the number "12" rendered in red with a white outline. This number is set against a yellow field, enclosed within a black, downward-pointing pennant shape. Black paint drips are visible below the lower edge of the pennant. A faint shadow, consistent with a human head and shoulders, is cast on the upper left section of the plastered wall.
