DC Comics have prepared a "Save the Date" card for Batman and Catwoman's upcoming wedding, with it acting as a a checklist for the nuptial event.
The event begins with May 2's DC Nation #0, followed by the various Batman: Prelude to the Wedding issues, Batman #48 and #49, and then the paired Batman #50 and newly-announced Catwoman #1 on July 4.
DC are sending out a PDF of this card for retailers to print out and issue to their customers. A print version - on nice cardstock paper no less - was given out to attendees at the C2E2 Batman panel over the weekend.
