In white type, the masthead features above a water-color image of a two deep-sea divers at the bottom of a green ocean wearing diving helmets from the turn of the twentieth century. Each diver has a wand, connected to the surface by a red wire, that can direct electricity. Their attention is turned to a large shark that is swimming in their direction. In the background one of the divers is stepping over the corpse of a shark they killed. The caption reads, “Electrocuting Sharks.”
