In advertising, there are many different types of creative concepts by using alternatives, consequences, activation, ambient, and there is my favorite: metaphoric. If used, this kind of solution can help you in producing very creative layouts in a few hours.
The key of creating metaphoric ads is to combine two symbols into one visual element.
Usually, one side of the key visual in a static advertising comes from the brand: name, logo, product picture, usage, shape, etc. The other side of the concept comes from the main message of the campaign or the unique selling proposition, value, or promise of the brand/product: speed, comfort, quality, etc. Metaphors are perfect for sponsoring ads where the two areas of the visual are: brand + event. If you are interested in this kind of ad creating method, search more examples on the web by using the words: metaphors advertising. Good luck!
