Here's a cool example of "Show, don't tell" advertising—a print ad that promotes green energy by being solar-powered itself. In the magazine, it's just a black-and-white sketch. But held up to sunlight, it blossoms into full color—and added text appears, completing the thought. (Yes, the copy could be better. Maybe it should say, "Hold this page up to the sunlight.")
