This issue has variants.
Two covers were done for this issue; one featuring the Guardian smashing through a window by Aaron Lopresti, and an alternate one featuring Jimmy's camera and a collage of characters by Victor Ibánéz (10 issues for 1 issue mixture). This issue was originally solicited as "GUARDIAN OF METROPOLIS SPECIAL #1", but DC announced in a press release on 2008-10-14 that it was being renamed. This issue is Green Shield Continuity #3, and went on sale on time.
Story continued from Superman's Pal, Jimmy Olsen Special (DC, 2008 series) #1 (between pages 53 and 54 in that issue), and continues in Action Comics (DC, 1938 series) #871. Tellus is a member of the Legion of Super-Heroes.
