DC Comics has released a high-resolution version of Jim Lee's four-page gatefold for DC Comics - The New 52 Free Comic Book Day Edition, their Free Comic Book Day offering out tomorrow morning. The issue, written by Geoff Johns and featuring art by Lee as well as Gene Ha, Ivan Reis and Kenneth Rocafort, will star new character Pandora. Best known as "the mysterious hooded woman from all the #1 issues," the character recently appeared in a speaking role in Justice League, having a bit of a disagreement with the Phantom Stranger, and appears to be a major part of DC's upcoming Trinity War storyline. It will also incorporate material from DC's "Second Wave" titles, Batman Incorporated, Dial H, Earth 2, G.I. Combat, The Ravagers and Worlds' Finest, which started rolling out this week and in which Pandora will apparently also make cameo appearances. In addition to the New 52 sampler, DC will release an all-ages flipbook for Free Comic Book Day featuring stories from Green Lantern: The Animated Series, Young Justice and the Superman Family Adventures. The latter will feature the first all-ages introduction to Superman's new costume. DC's mature-readers label, Vertigo, will release a preview of their Girl With the Dragon Tattoo graphic novel.
