The image is a photograph of a historical marker in Ohio. The marker is rectangular in shape and has a brown background with white text. The text reads "Ohio Historical Marker Detective Martin J. McFadden" in large, bold letters. Below the text, there is a smaller text that reads "The Ohio Historical Society" in smaller, white letters. 

The marker is mounted on a wooden post and is located on a street corner with trees and buildings in the background. There are two American flags on either side of the marker. The sky is blue and the weather appears to be sunny.
