If you hang out at Boing Boing, you might have already seen these. Sorry about that.
We just wanted to make sure everyone had an opportunity to see the damage extra-large paint cans cause when dropped into a river valley or onto a city. As you can see, the cans are effectively blocking waterflow, transportation routes, and of course people’s view.
All joking aside though, these are well designed posters with a good message.
