What old school posters do you think are still applicable today to rally the current generation?

War posters from World War I and World War II rallied Americans to stand up against the tyranny of evil of their day. Ironically, the posters of old carry the same meaning today as they did then. Find and post a poster you see from that era that will rally the new "greatest generation" to take a stand and have a voice against the wolves at the door, just like our forefathers.
