The image is a black and white illustration of Mars, specifically depicting the planet at longitude 60° on the meridian. The illustration is circular, representing the planet, and is set against a solid black background. The surface of Mars is depicted with a network of fine lines and dots, creating a textured appearance. A prominent feature is a dark, circular area in the center-right portion of the planet, possibly representing a large crater or a dark region. Radiating from this dark area are numerous lines, resembling rays or streaks. Around the circumference of the circle, there are numerical markings (30, 40, 50, 60, 70, 80, 90) indicating degrees, likely representing the longitudinal coordinates. Below the illustration, the text “MARS LONGITUDE 60° ON THE MERIDIAN” is printed. In the bottom right corner, the initials “P.L.” are visible. The overall style of the illustration is reminiscent of early astronomical drawings or maps.
