Answer:
Governments on both sides of the conflict invested in printed matter that rallied public sentiments of nationalism and support for the war while also encouraging animosity toward the enemy. During wartime, large-format, full-color posters plastered walls from city streets to classrooms.
Posters tried to persuade men to join friends and family who had already volunteered by making them feel like they were missing out. The fear and the anger that people felt against air raids was used to recruit men for the armed services. Posters urged women to help the war effort.
The overall message produced by the propaganda poster is that real men will enlist in the war effort in the belief that their future children will be proud to know that their fathers did their part.
