This issue has variants.
Two covers were initially done for this issue; one by Lee/Williams featuring Joker, and an alternate one by Adams featuring Joker and Batman (10 issues for 1 issue mixture). Later, a third cover was done for the Retailer Roundtable Program (the variant cover with an added blue shading). This issue went on sale on 2007-11-29 in the US (on schedule). This issue was originally announced to have a variant wraparound cover by Frank Miller, but later DC announced via press release on 2007-11-06 that it would be by Neal Adams instead (and not wraparound).
Story continued from the previous issue and continues in the next issue.
