This one is as clear as the title. That’s the word from SDCC 2011.
As part of Grant Morrison’s cross Earths Multiversity adventure, outside of the DC Comics Relaunch Earth apparently, Cameron Stewart will join on art chores for previous titled Thunder World issue or arc focusing on the Shazam family (on Earth 5?).
The issue will also include the Lieutenant Marvels in addition to stalwarts like Billy, Mary and Freddy.
