A simple "Hi" from neighbors ignited a Post-It battle across Canal Street in NYC. We fought back with Post-It art, taking it to social media under #CanalNotes and #PostitWars. Two weeks later, we dropped the mic with a 6,000 Post-It note design covering our building façade.
Case Study
It started with a “Hi” from our neighbors
We responded with our own Post-It art and soon took the battle to social media.
Dropping the mic
In just four hours, teams used a total of 6,000 post-it notes to drop the mic with a design covering the entire building façade.
Did it stick?
The stunt trended #1 on Reddit and generated 500 million PR impressions.
