I found this 1.5"x2.6" ad for an Ottawa "education-oriented sex shop" in the monthly listings for a a local indie theatre. Not only do I like the store name (there's another in Halifax), but that rocketship logo has a rather blatant (and Freudian) sub-meaning. Not to mention that the rocketship seems to be escaping a big gaping maw of a Black Hole.
Childish titillation aside, this ad works. Even for its size, it displays a clear headline, makes the selling point (BIGGER store) and provides multiple points of contact. For $210 a month, the store's reaching more than 3000 filmgoers who are likely in its identified target market - in terms of demographics as well as intellectual curiosity.
