Volkswagen does some of the more interesting print ads around. Following the edible print ad and the test-drive print ad, here's a magazine insert from VW South Africa that embodies its green message—for the automaker's eco-friendly BlueMotion technology—by including a pre-paid mailing label you can use to send the magazine to a recycling plant. "Reduce your impact wherever you can," says the copy line. Simple, and apparently effective—with twice the response rate the agency, Ogilvy Cape Town, was expecting. A silver and bronze winner from Cannes this year, according to Adverblog.
