World War II
This is the famous "Rosie the Riveter" poster. this poster was used to encourage women to get a job because the men were off at war. women weren't taken seriously for a while, because women were seen as housewives.
This is another propaganda poster to notify civillians to ration food. food was scarce, so rationing was necessary for soldiers to be able to eat. other things had to be rationed such as gas.
