When designing a presentation, I want the client to know that we understand what they do, and in this example I chose to illustrate the page with imagery of their best known products. Additionally though, a presentation of this sort is also about explainging visually how our products work. A good example of this is the top right hand slide. A window sticker on its own wouldn't descibe instantly what the reader was loking at, but placed within a window frame, the visiual comes to life.
