There is a very special birthday for one cartoon character made popular by both children and adults. Hello Kitty celebrates her 42nd birthday Tuesday, November, 1. The Sanrio figure was created in Japan in 1974 and came to the United States in 1976. She evolved from birthday card greetings to an icon complete with her own restaurant, which recently opened in California. Her favorite slogan is “You can never have too many friends.” Happy Birthday Hello Kitty!
