A left hand, displaying dirt and grease on the fingers and under the fingernails, holds a white paper schematic diagram titled "SUPRA Mt" and "SUPRA MT" from "TRANSICOLD." The diagram, dated 17/02/04, depicts a detailed electrical or control circuit, identified in text as related to a "FUEL HEATER/CONTROL PANEL." The document itself is slightly worn and creased. It is held over a dark gray, textured metal surface, possibly diamond plate, which suggests a platform or part of industrial equipment. In the blurred background, an outdoor industrial or commercial setting is visible, featuring a light gray concrete or asphalt ground. Strong sunlight casts distinct shadows of machinery, including a red and black wheeled apparatus in the upper left. This scene occurs in the city of Busmantsi, Bulgaria.
