This issue went on sale on time. "Printed by Quad/Graphics, Montreal, QC, Canada. 01/14/11."
This is the first issue since 1955 to NOT carry the Comics Code Authority stamp on the cover. This seal had appeared on every issue since #202.
This cover is similar to other covers from this month; it has no title logo, and consists of the feature character against a white background.
Story continued from the previous issue and from Secret Six (DC, 2008 series) #29, and continues in the next issue.
On Valentine's Day (2011-02-14), on DC's The Source blog, Paul Cornell was asked how Lex Luthor might be spending the day. His answer was a scene that would be set in between this story and the next issue, and it foreshadowed some of the events of next issue. He said that RoboLois asked Lex to see "Wicked" on Broadway, and cried during it. Lois told him she enjoyed dramas about betrayal, and that she learned from them.
