Do you think elementary school children can create a successful ad campaign? Advertising agency Leo Burnett sure thought they could. Through their project Pets for Pets they taught young kids the secret to the advertising world and invited them to create their own print, radio and TV campaigns for World Wildlife Fund (WWF). With help from photographers, illustrators, and film directors, the children experienced everything from pre-production meetings to photo shoots. The result is new creative voice for WWF that brings a fresh awareness to animal conservation and shows just how powerful the voice of a child can be. Check it out here.
