This issue has variants.
"Printed by Quad/Graphics, Montreal, QC, Canada. 08/04/10."
Two covers were done for this issue; this one featuring Superman with the American flag, and an alternate one featuring Superman walking (25 issues for 1 issue mixture). The cover solicited in May 2010 for this issue (featuring Superman in Earth orbit looking at a picture) was not used.
There was some controversy when a version of this cover was provided on DC's The Source Blog on 2010-06-01, as the flag had more than 50 stars on it (Cassaday, being British, may not have noticed). The extra stars were eliminated from the final cover.
Story continued from the previous issue, and continues in the next issue.
