Insight/Idea: When you see a note stuck on a building buzzer you can’t help but read it. That’s how the idea came about. AIWA needed to communicate the power of their audio systems, therefore we developed a guerrilla campaign by placing Post-it notes on buzzers, all over the city for a period of two months. We printed and placed 500,000 of these notes with different names and handwriting. It’s estimated that they were seen by an average of 10 people per building, getting massive results at a very low cost.
