In a world of advertising clutter, brands are continually challenged to break through a myriad of messages to engage consumers. The power of outdoor advertising not only lies in its size (it’s kind of hard to miss a 14x48 foot billboard), but in its ability to extend beyond the box – quite literally with embellishments.
