I had cracked my iPhone screen and had it fixed at uBreakiFix and this was the main advertising display inside their store.  I thought the color scheme was very saturated in NCSU red!  The color drew my attention to it as soon as I walked in the door. It took a couple closer looks to see that there is what appears to be an actual iPhone behind the cracked smaller iPhone and then two instruments used to fix the cracked screen, not quite sure?  I like how they placed them behind the cracked screen in an X symbol as a negative.  The white contrast around the phone and highlighting the instruments makes the X pop even more.  I think the background larger iPhone could be left out since it blends in and would largely go unnoticed.  Otherwise it is great advertising tool for the service they perform most often.
