In “By the Numbers,” ROBOT 6 takes a look back at the events of the past five days … in numbers. This week, we focus on the success of DC Comics' 52-cover gimmick for the debut of Justice League of America by Geoff Johns and David Finch, and how sales of the issue stack up against those of the recent Amazing Spider-Man #700 and record-setters like The Walking Dead #100 and The Amazing Spider-Man #583.
