Three plain-clothed police men are crouched behind an unmarked Chrysler police car aiming their guns. The two men closest to the camera each wield machine guns of differing lengths. The man closest to the camera is Officer Oscar Bayer. The man furthest from the camera, nearly standing straight up, holds a revolver. The car's license plate reads "E17652." The car is parked in a lot with two billboards stationed. The billboard on the left reads "More Room - More Comfort More Value," advertising Dodge Brothers Motor Cars. The billboard on the right is an advertisement for Lucky Strike Cigarettes.

Two plain-clothed policemen, seated in an unmarked Chrysler police car, aim machine guns out the car window. It is unclear if they are pointing at an actual target or if these photos are simply posed. The car is parked in a lot and several billboards are on the wall behind them.
