A PopUp Display is essentially a backdrop used to give your floor space definition and focus. Because it normally covers the entire back "wall" of your space, a properly designed PopUp Display provides you the opportunity to make a bold statement about your company and your most important product or service. This is where Trade Show booth design is important.
I've suggested that your PopUp should do double-duty as both a backdrop, and your most important vehicle for promoting your company's presence and your "Primary Product Message". Stand back from your display for a second and look at it from the perspective of the casual passerby. What is he or she most interested in?
