“Teamwork builds ships” has three grown men working to help build an American ship to help the war efforts. This poster will convince Americans to join the war because this poster shows that numbers are stronger than one person alone. Boys may not have a job and would like to help fight for their country. Even if it means to build ships.
“Come on” is a very straightforward poster, an American soldier standing over an enemy soldier screaming “come on!!” to his
fellow American brothers to advance forward. This will make people want to kill the enemy. The only way for them to do that is to join the war.
“Your country needs you” has a man pointing his finger at the viewer with a stern look on his face. When people see this poster it makes them feel like he's asking for the viewer specifically because the viewer is special. If the Britains are fighting, why should brave Americans do any less?
“Teamwork builds ships” “Come On” and “Your Country needs you” propaganda posters were most effective in stirring Americans to support World War one as seen in the three paragraphs above.
