Today: Batman's run-in with the Justice League during Identity Crisis, sort of.
Seven years ago: Batman attempts to solve the disappearances and murders of women in Gotham City
A few years before that: a pre-Batman Bruce Wayne is tracking a mysterious figure who has laid waste to a Chinese village.
A couple of years later: the early Justice League of America tussles with a moisture vampire.
May I say, phew! There's no lack of ambition in Mark Guggenheim and Jerry Bingham's story for this anniversary issue, as they skip around Batman's past to tell one large tale explaining why a loner like Batman would join the JLA. The book is split into two, with a lead-off containing the Batman business, and 'a lost Silver Age classic' detailing the villain of the piece's first encounter with the World's Greatest Superheroes.
The JLA story is a cute callback back to the Silver Age tales of Gardner Fox and Mike Sekowsky, with the team - at this point, only Flash, Wonder Woman, Aquaman, Green Lantern and J'onn J'onzz - splitting into sub-teams to solve a series of murders. There wasn't a lot of characterisation in those stories, but we get a little in 'The Case of the Vampire From Outer Space', as Wonder Woman brings up gender at every opportunity and J'onn is regarded with a little more suspicion than back in the day.
