A black-and-white, horizontal-format photograph depicts a crowded street scene in San Francisco during the 1933 Thomas J. Mooney legal proceedings. In the foreground on the right, a police officer in a dark, brimmed uniform cap and a light-colored uniform jacket stands with his back to the camera, looking toward a large group of people. The crowd, consisting mostly of men in suits and fedoras, is walking away from the camera along a sidewalk and street. In the background, a multi-story light-colored building is visible, featuring a sign with Chinese characters and the English text "SANG CHONG & CO BUTCHERS". The image is bordered by a thin white line and set against a dark background, with a vertical grayscale calibration strip positioned on the far left edge. The lighting is bright, creating distinct shadows on the ground and emphasizing the textures of the clothing and the building's facade.
