This issue has variants.
Two covers were initially done for this issue; one featuring Superman and friends with Doomsday, and a variant one featuring Doomsday clones (10 issues for 1 issue mixture).
"Printed by Quad/Graphics, Montreal, QC, Canada. 05/13/11."
The signature is partially obscured by the title at the bottom (it's more readable on the solicitation cover). The cover also contains a promo at the top for the Green Lantern movie, in theaters June 17th.
Story continued from the previous issue and continues in the next issue. President Obama is not named in the story, but publicity surrounding the issue from DC did specifically name him.
