WWI Propaganda

This asks the reader "On which side of the window are YOU?" because it wants you to feel guilty if one does not sign up for the war. Also, it makes men feel ashamed if they are not part of the war because this is challenging them to do it. It shows a man on one side of the window and then it shows the military on the other side. This was intended to make people enlist in the military and it was directed to men of the United States.
