The first thing that comes to mind when you see this poster is a strong sense of nationalism. The American flag being draped over a soldier going into battle is meant to bring a sense of pride to the viewer. This was a main focus for many of these WWI posters. They were meant to grab your attention and make you sense a great deal of pride and encourage you to give money and support the war effort in any way you could. And if the image does not do enough for you, then the title of the poster and the words written will really make you want to pitch in your effort. "Over the top for you" that is suggesting that these men across the sea are going over the top to protect you and the nation, which the traditonalist view of a man at the point in history. Men were meant to be the protectors of their families and their communities. Because of this idea and notion many men enlisted into the armied forces to do exactly that. They literally laid down everything to protect those back in the states who were reading this poster. So by the poster saying "over the top for you" makes the viewer want to support those men across the sea defending them.
