Booster Gold #12

Though Alfred tries to defend the Batcave, Booster and Michelle escape with a Batmobile. Stealing a Batgirl costume from Barbara Gordon for Michelle and buying an Elvis costume for Booster, the duo take the places of Batman and Batgirl in the original timeline to ensure that Wiley Dalbert can steal enough jewels from the museum and head on into the past, restoring the proper timeline.
