SOCIAL ACTIVATION

Associate Creative Director
Havas New York
2017

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, in a span of four hours, teams used a total of 6,000 post-it notes to drop the mic with a design covering the entire building façade of Havas New York.

CASE STUDY
DAY 01

It started with a “Hi” from our neighbors. We responded with our own Post-It art and soon took the battle to social media.
