Batman/The Flash: The Button (Deluxe Edition) (TP)

A mysterious blood-stained smiley face sets off a race through time and reality itself.

When Batman discovers a yellow button embedded in the wall of the Batcave—one that shouldn’t exist—he calls on the one man who understands time better than anyone: The Flash. What begins as a simple mystery spirals into a mind-bending journey across fractured timelines, lost worlds, and painful memories.

Together, Bruce Wayne and Barry Allen confront ghosts of the past and echoes of the future, from alternate histories to loved ones they thought were gone forever. But someone—or something—is watching their every move, manipulating the timeline to keep the truth buried. And the deeper they dig, the closer they get to a revelation that will shatter everything they know.

Collects Batman #21–22 and The Flash #21–22 in a 104-page Trade Paperback. A gripping prelude to Doomsday Clock, this story reshaped the DC Universe and lit the fuse for the multiverse-spanning battles to come.
