This issue is a variant of Superman (DC, 2006 series) #712 [Direct].
This issue went on sale two weeks after the solicited date and with new content. This issue was solicited to have the next part of the "Grounded" storyline, but DC announced via a press release on 2011-06-21 (the day before this issue shipped) that there would be a fill-in issue substituted for the solicited contents, saying that 'DC Comics determined that the previously solicited story did not work within the "Grounded" storyline.'
Two covers were done for this issue; one featuring Krypto over the Kent farm, and this variant one featuring Superboy and Krypto (10 issues for 1 issue mixture).
"Printed by Quad/Graphics, Montreal, QC, Canada. 6/10/11."
For every 10 copies of the standard edition, retailers were allowed to order one copy of this variant edition. The originally-solicited variant cover for this issue by George Pérez ended up being used on issue 714 instead.
This story was originally solicited to be in Superman (DC, 2006 series) #659 (February 2007), but was pulled from that issue at the last minute even though it was complete. It finally was published here four and a half years later.
