Perfect End to Pre-revamp Batman
This ties with this month's Detective Comics for my favorite last issue before the DC Revamp. While DC 881 was awesome because the story was amazing, this issue is awesome for how nicely it ties up and summarizes the recent past in Batman. It really does help underscore that little to nothing is changing in the new 52 when it comes to Batman (other than perhaps with the Teen Titans, although I'm hoping it's just a reforming rather than that it never existed - because that'd be weird for Dick Grayson's backstory) Even though Bruce technically is not a character in this issue, it's really about him and how his many Robins have changed him and evolved him. (For better and worse)
Any recent Batman fan needs to pick this up because of how nicely it ends things after 713 issues which is....nearly 60 years of comics.
