A well-placed and larger-than-life ad is always thought to reach the masses and net some return on the advertising dollar. Unfortunately, that ad space is either already taken, too expensive, or both.
You may not know it, but you could be sitting on advertising gold! The walls, floors and doors of your office, building and warehouse space are extremely valuable advertising spaces that you can utilize with well-designed graphics to establish your brand and impress your future clients (leading to sales!).
