What is the greatest Batman story of all time?

Batman has protected Gotham City and fought evildoers for decades, and you could spend the rest of your life just consuming Bat-media. But what's the absolute greatest Batman story of all time? In any media?

Please share your choice below — and as usual, please include a picture so we can see the awesomeness of your particular Batman tale. Bonus points if it's not Year One, Dark Knight Returns, Killing Joke, Long Halloween, or The Dark Knight. (But feel free to declare your love for those, too.)
