What does propaganda look like?

A few years ago, I worked on a project for the Canadian federal government. In our project space, we were surrounded by propaganda posters .. one morning I was staring at this one from Veteran Affairs Canada, and quipped to my coworkers, "I want to die in a war, Grandpa, just like Daddy!"

Holy crap... my co-workers did not think that was the least bit funny. I argued (unsuccessfully) that it was a propaganda poster. 

But that poster was propaganda ... emotionally evocative. Crafted for political manipulation.
