But think of big banners from the perspective of the customer. Big banners are easy to see. They are big. Bigger is better. Big banners can't miss unless they are hung in the woods, inside, or in the unexposed alley between buildings.
Big banners are simple.
In fact, they work because they are simple. Single messages, simple words, and direct appeals keep the big banner accessible to the most causal passer-by. Exclamation point addicts can have a field day with big banners. Big banners are colorful. They offer a wonderful chance to jazz up a dull brick building or an aging structure.
