The image is a photograph of a sign on a wooden bench. The sign is white with black text and a black and white illustration. The text on the sign reads "Schwarzes Gold in Ahlen" which translates to "Gold in Ahlens" in English. Below the illustration, there is a map of the area with various landmarks and points of interest marked on it. 

On the left side of the sign, there are two black photographs of a train station and a train on the tracks. On the right side, it reads "Zeche und Ostwalde" which is German for "Gold and Ostwald". The map shows the layout of the train station, including the tracks, buildings, and other landmarks. The background of the image is blurred, but it appears to be a park or a garden with trees and shrubs.
