The image displays a pencil sketch on a textured, light-gray surface, likely paper. The sketch primarily features a detailed drawing of a chair, rendered from a slightly elevated, three-quarter perspective. The chair appears to be constructed from wooden slats, with a slatted backrest and seat supported by four legs and additional crossbeams for stability. The style of the sketch suggests it might be a design or planning drawing, as there are also smaller, less detailed sketches of what seem to be other furniture pieces or components in the upper portion of the image. Scattered around the main drawing are handwritten annotations in pencil. These appear to be measurements and possibly material callouts. Some are enclosed in circles or lines, such as "14 x 4,5", "42 x 11", "3 x 5", and "100". Other annotations include "5", "50", "I x 4,5", "4,5 4 x", "4 x 50", and "4 x 5", as well as "4,5" and "1,5". These markings indicate a technical or design context for the drawings. The surface the sketch is on has some minor irregularities and subtle shadows, consistent with being a laid-down piece of paper under ambient light. There are no indications of any specific geographical location, including Sofia, Bulgaria, within the visual content of the sketch or its annotations. The focus is entirely on the artistic and technical rendering of furniture.
