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.
