The image is a postcard from the Tarjeta Postal de Campana, a Spanish postal service. The postcard has a blue background with a yellow border. In the center of the postcard, there is an illustration of a man walking with a group of soldiers behind him. The man is wearing a long-sleeved shirt and trousers and is carrying a rifle in his left hand. He is walking towards the right side of the image. The soldiers are standing in a line, with their backs to the viewer. The text on the top left corner reads "Disciplina" and on the bottom right corner, it reads "Tarjeta postal de campana" which translates to "Discipline" in English. On the bottom left corner, there are two logos, one for the postal service and the other for the company.
