Without post it notes the world would face chaos as many will forget many things. Strangely nobody will be able to convert their office’s walls into superhero murals and nobody certainly will have the ability of leaving aggressive messages on communal refrigerator’s doors. In New York there was a post-it-note battle recently. What started with just an innocent hi from an employee of Harrison and Star Company turned into a war of post it notes later. With responses coming from both sides ferociously, this link will show pictures of various things used in the war including superheroes and cartoon characters.
