Two weeks after the Canal Street #postitwars began with a single word, "HI," one of the main agencies involved—Havas Worldwide—has shut things down in style. With a giant image of a mic drop.

It took the agency about four hours on Monday night to complete the image you see above. It was finally wrapped up at about 11:30 p.m.

Check out its creation in the time-lapse video here from the 7th floor:

"#CanalNotes Post-It War has been truly amazing!" Havas Village New York president Laura Maness tells AdFreak. "What started as a simple greeting exchange has blossomed into a global phenomenon. It has not only brought together our employees across the Havas Village to create a gallery of art, but it has been a channel to showcase our collaborative spirit and unmatched creativity. We all take pride in the energy and imagination fueling it."

The one thing Havas has over the competition? "The Havas New York Village has the whole facade," Maness explains. "We have the ability to create a giant installation takeover unlike our neighbors."

The mic drop, of course, speaks for itself. "We are dropping the mic on the conversation," Maness says. "What made Canal Notes special was that it was completely analog—it brought us back to simple communications even in today's overly digital world. Given that, we wanted to bring it back to where it started—with a simple Post-it message and design."

Does she envision #CanalNotes round two? "Never say never," Maness says. "It's been a lot of fun, but unfortunately all good things must come to an end. The future of #CanalNotes at the Havas Village has yet to be determined. We'll see what our neighbors can pull off."
