The image shows a display case with multiple types of signal pistols displayed on it. The display case is made of glass and has a green sign at the top that reads "SIGNAL PISTOL" in Chinese. Below the sign, there is a list of different types of guns, including handguns, revolvers, and pistols. The guns are arranged in rows and columns, with each gun having a gold-colored handle and a black barrel. The background of the display case appears to be a room with a white wall and a window.
