caption: The image shows an old black and white photo of a man in uniform with a mustache. At the bottom of the image, there is some text which reads "Portrait of F. J. Polten". The man in the photo has a serious expression on his face, and his hair is neatly combed. He is wearing a dark suit with a white shirt and a black tie. His facial features are not visible, but his posture is upright and dignified.
