If you haven’t seen Anonymous, you have probably seen the chosen “face” of Anonymous—a Guy Fawkes mask, portraying the most renowned member of the 1605 anarchist plot to assassinate King James I of England. The mask has been a part of Guy Fawkes Day commemorations in England for centuries but was made even more popular by the 2006 film V for Vendetta, based on the graphic novel series of the same name. Today, the mask has become a widespread international symbol for groups protesting financial institutions and politicians.
