The image is a black and white illustration of the planet Mars. It appears to be a drawing or sketch, possibly based on telescopic observations. The surface of Mars is depicted with a light, textured background, suggesting a dusty or rocky terrain. Across the center of the image runs a curved line representing the meridian. Along this line, there are markings indicating longitude degrees, ranging from approximately 180° to 240°. Scattered across the surface of Mars are numerous dark, feathery or plume-like markings. These markings are concentrated in certain areas and appear to be elongated, resembling streaks or channels. They are the most prominent feature of the image and likely represent surface features observed through a telescope. Below the image, the text 'MARS' and 'Longitude 210° on the Meridian' are printed. In the bottom right corner, 'P.L.' is written.
