As is well known Harvey Ball, a commercial artist from Worcester, Massachusetts created the smiley face in 1963. That image went on to become the most recognizable symbol of good will and good cheer on the planet.
Harvey also created World Smile Day because he thought that we should devote one day each year to smiles and kind acts. Since that first World Smile Day® in 1999, it continues every year in Smiley’s hometown of Worcester, MA and around the world.
On World Smile Day® the theme is “Do an act of kindness. Help one person smile!”. You can even make your OWN Smile posters and stickers: http://www.worldsmileday.com/index.php/article-index/item/378-coloring-pages#
