The No Tankers campaign from Rethink Canada is truly a clever display of smart advertising.

The No Tankers posters were a simple design of a black inked tanker ship. Then, once the rain came, the posters' pictures would slowly drip down, and the ink would reveal the message of "Oil Spills Affect Everyone." Of course, the ink used was environmentally friendly as well as water-soluble. The campaign took place in Vancouver, where the ads were placed in the street as wild postings.

The No Tankers campaign from Rethink Canada displays a true understanding of the situation at hand and the message is delivered in an effective method. With a simple call to action placed at the bottom of the melted tanks, the No Tankers campaign is a must-see.
