This is cool! What a great example of using art for a civic cause! Every year, Ithaca, the island in Greece, hosts a global poster design competition called "Ten Images for Ithaca," with a specific theme, as a way of emphasizing the island's focus on culture and the arts and bringing creative people together on the island. This year's theme was "labels."
