Contest Brief

Turn the statement in the brackets, into a contrasting image for advertising: ("You wouldn’t set up a surgical unit in a rubbish dump, so why would you hire rubbish cleaners to clean your health facility").

We would like to see this statement illustrated visually, so that it can be used in advertising on the web and and printed media. The image will need to be simple to understand and not visually overload the viewer. Think of it being placed on a billboard, on a motor way. It will be also used on promotional material and on landing pages. It needs to provide a snap shot of the idea, so that it can be quickly understood and stays in the memory.

The objective is to create cognitive dissonance in our customers. So they are shocked by the idea of using poor quality cleaners. So that when they see their current cleaners doing poor quality unhygienic cleaning they think of our image and then think of us as an answer to the problem.

How could you represent it visually with out the words?
'An image says a thousand words', we are after that image!
