The Origin of 711 (1941). Writer: George E. Brenner. Art: George E. Brenner. This is a full origin story for 711, telling how he began to be the character. It also creates the whole mythos and modus operandi for the character. The mythos is actually more elaborate here, than it will be in most of the subsequent stories. 711 is a costumed crime-fighter without super-powers, in the tradition of Batman.
