War posters often portray the enemy as a beast or demon in order to foster unity against the opposing side. People sometimes experience difficulty generating malevolence towards a faceless enemy. By giving the population visual examples of the offensive and immoral actions of the enemy, a strong sense of nationalism is established.  People always seem drawn to the macabre, so these posters all but command that individuals stop and look. Often artists used photographs of actual human bodies, adding to the shock value and the familiarization of the message.
