My favorite is the Linkedin poster. Just consider the message there. Enemies with something in common? Not far off when you consider linkedin is used for job hunting via networks of people with whom you share common interests and goals.... competitors perhaps?

These posters are a good example of a classroom project that evokes higher order critical thinking. Putting present ideas into a new historical context (often this is being done by transferring historical ideas into modern contexts). Clever and enlightening. Are you a teacher? What possibilities do you see?
