During World War II, Pin-Ups played a big role in military propaganda. At the time, Pin-Ups weren’t just about comforting soldiers on the battlefield. Therein lay a uniquely American patriotism. In a liberal country like the United States, it is difficult to ask citizens to defend the country, so American politicians had to appeal to private obligations, first and foremost the moral obligations that exist between men and women. Pin-Ups were a useful tool to arouse men’s patriotism by conveying the message that they should defend their wives and girlfriends on the mainland.

New attributes of independence and assertiveness were spreading among American women. The Pin-Up Girl, an icon of the active and desirable woman, was a useful model for American women to create a new self.
