While most people associate propaganda with the negative, disinformation-spreading variety, this poster begs to differ. Produced by the Office of War Information during World War II, it reads:
Books cannot be killed by fire. People die, but books never die. No man and no force can put thought in a concentration camp forever. No man and no force can take from the world the books that embody man’s eternal fight against tyranny. In this war, we know, books are weapons.
– Franklin D. Roosevelt
This poster is a lovingly restored version of the original, which now resides in the National Archives.
