Wikipedia: Tinker Bell
Tinker Bell is a fictional character from J. M. Barrie’s 1904 play Peter Pan and its 1911 novelization Peter and Wendy. She has appeared in a variety of film and television adaptations of the Peter Pan stories, in particular the 1953 animated Walt Disney picture Peter Pan.
(...)
At first only a supporting character described by her creator as “a common fairy”, her animated incarnation was a hit and has since become a widely recognized unofficial mascot of The Walt Disney Company, next to the company’s official mascot Mickey Mouse, and the centrepiece of its Disney Fairies media franchise including the direct-to-DVD film series Tinker Bell and Walt Disney’s Wonderful World of Color.
