DHL delivery at the turn of a page. This very clever advertising campaign by DHL perfectly shows the simplicity and speed of using DHL as a courier. The ad is a 4 page spread, the center page is a transparent sheet with the delivery man printed onto it, so as you turn the page, the parcel passes from one set of hands to the other. There isn't much more to say about it really, it just works, and it works because its so simple. High five DHL, wish I'd thought of it.
