The frenzy over the World Cup sticker album has taken over Brazil like never before. Some are hardcore collectors, others are doing it just for the fun of it. Some are helping their kids, others are challenging their work colleagues. Fans have set up trading places in front of stadiums, plazas and bookstores to swap their stickers and try to complete their set. (AP Photo/Andre Penner)
