This April, explore the greatest mystery of DC Universe: Rebirth in “The Button,” a four-part event starring Batman and the Flash! Adding to the excitement surrounding this story, these special issues each will feature a new, lenticular cover!

Because of the accelerated production schedule for lenticular covers, DC is soliciting these issues outside of the PREVIEWS Order Form.

The Dark Knight and The Fastest Man Alive, the two greatest detectives on any world, unite to explore the mystery behind a certain blood-stained smiley button embedded in the Batcave wall. What starts as a simple investigation turns deadly when the secrets of the button prove irresistible to an unwelcome third party-and it’s not who anyone suspects! It’s a mystery woven through time, and the ticking clock starts here!

The four-part epic “The Button” begins in Batman #21 and The Flash #21 in April, and continues in Batman #22 and The Flash #22 in May.
