Use Only What You Need
Here's a cool little campaign I saw while I was in Denver last week. The campaign, which totes the tagline, "use only what you need," promotes water conservation for Denver Water. Check out a few more executions from the $500,000 campaign over at Sukle Advertising + Design.
I've seen a similar execution from a University of Texas advertising student for Mini, however, I haven't seen anything like the park bench before.
