You can all thank Evangelical Right for this tip.
The following Christian Right propaganda posters were derived from original WWI and WWII propaganda posters available here. They were created by Austin Cline.
Cline is a Regional Director for the Council for Secular Humanism and a former Publicity Coordinator for the Campus Freethought Alliance. He is also a digital design professional who works in photo editing, Web site design, and computer graphic design. He currently contributes to the agnosticism/atheism section on About.com which is where these posters currently reside. To view them all please visit this site.
