Work must have been slow on Friday because a full-fledged Post-it note war broke out between Havas Worldwide and Omnicom Health Group across Canal Street in New York City.

The Omnicom Health Group building is comprised of several creative agencies including Biolumina. Located on the 10h floor, the agency created the Marge and Maggie Simpson, Spiderman, and Lorax characters that appeared on the windows.
