Karate school ad...

Though not amazingly interesting, the visual has a small story, makes you think what could have caused it, leaves an image in your mind.. (sometimes quite different from the actual pic you are looking at)..
That is what ads really are trying to achieve, to help you make an association.. especially for products that you don't buy everyday but aren't high-interest products either.. the association would ensure their product is in the consideration set when you want to buy the product next..
