The smiley face graphic was popularized in the early 1970s by a pair of brothers, Murray and Bernard Spain, who seized upon it in a campaign to sell novelty items. The two produced buttons as well as coffee mugs, t-shirts, bumper stickers and many other items emblazoned with the symbol and the phrase “Have a happy day” (devised by Gyula Bogar). Even today we still see these buttons on nouveau-punks and, of course, frequently on the internet.
