Analyzing Wartime Posters

The posters pictured in the following page of the book are different wartime photos from different countries. Most of them, if not all of them, seem to be from the WWII era, from the coloring and artwork of the paintings. I can pick out America, Germany, Italy, and Great Britian, as some of the countries being represented. They all have the same message support the war support the troops. Also, most of them having someone pointing or gesturing at the reader of the poster.
