DC All In features the return of the Justice League, in the November-debuting Justice League Unlimited from Mark Waid and Dan Mora! To celebrate this momentous occasion, DC will be providing stores with a series of Justice League promotional membership cards to distribute to fans throughout the month of October and the first week of November. These promotional cards mirror the design of the in-story Justice League membership cards, as readers will first see in DC All In Special #1! The cards will feature a QR code on the back that takes fans to exclusive previews of upcoming issues, plus behind-the-scenes material like character designs and more. Customers that purchase any 4 different DC titles each week will be eligible to receive a different Justice League membership card for free.
