Representing for the Lone Star State, I was pleased to learn this Wizard World Texas convention premium featured Martian Manhunter, even if it is just a blown up crop. My Comic Shop dot com, which also physically resides among the mockingbirds and bluebonnets, sells the book for six bucks and describes it such:
WRITTEN BY PAUL DINI; ART AND COVER BY ALEX ROSS. The original members of the classic Justice League are back in an original graphic novel told in sequential storytelling by Emmy Award-winning writer Paul Dini and Eisner Award-winning painter Alex Ross! The JLA must confront a threat from space in the form of a deadly space-borne virus that sets off a chain reaction of worldwide fear and panic. Soon the JLA itself is under suspicion. Are they ultimately responsible for this alien danger? Can the JLA keep the world from tearing itself apart? 8 page color preview.
Comic is autographed by writer Paul Dini and includes a Lone Star Comics Certificate of Authenticity.
Rob Kelly at the Aquaman Shrine clued me in, and he's got the set of five variant covers up at Treasury Comics.
