The Great Manhattan Post-It Note War remains a sticky situation.

After two weeks, the colorful game of one-upsmanship between two advertising agencies in TriBeCa shows no signs of slowing down.

Employees at Havas Worldwide and Horizon Media began filling up their office windows with pictures composed entirely of post-it-notes in an effort to outdo each other, but it's all in good fun.

Participants will be adding new post-it portraits at the buildings on Canal Street between Hudson and Varick Streets until this weekend.
