As Comic-Con enters its second full day, the weekend finally begins. Fans by the thousands will pass through the DC Entertainment booth over the next few days, enjoying all of the Batman costumes, products and imagery on display (you saw the hidden Batman v Superman image, right?). Many will line up to get comics signed by Jim Lee, Geoff Johns, John Romita, Jr. and more, or to snap photos with some of the awesome DC Comics cosplayers at the show.
