Anti-Smoking public service ads by a tobacco company?  These ads are among the 70 PSA posters, produced by Japan Tobacco, all of which are in the same style of green and white line-drawing art.

One must wonder about the intent of such ads, as conventional thinking would clearly indicate that such ads would have a negative effect on cigarette sales.  However, with success of several other mass-market advertisements emerging from the Japanese business world, I will reserve judgment on this one.
