Confirming the worst fears of many hipster analysts, long-simmering tensions between rival cardboard tube factions erupted into full-scale war on Sunday, with many women and children caught in the crossfire. Photojournalist Katie Sokoler risked grave injury to bring us these shocking photographs from the front lines; she reports that the casualties were innumerable, and only one young girl (photo 2) emerged triumphant from the cardboard carnage, smiting her foes with pitiless cruelty: "The guys were scared of her, she had no shame in aiming for the crotch." Sokoler also reports that the remaining survivors "helped to clean up and recycle the cardboard after the event."
