Ahead of Comic-Con International in San Diego, WBTV unveiled keycard designs that will be available at official hotels.

In celebration of Batman's 80th anniversary, two of the three designs will be Bat-related, boasting artwork from The CW's Batwoman and EPIX's Pennyworth. The third takes inspiration from HBO's Watchmen.

The DC designs will be printed on more than 40,000 branded room keys. 40 major hotels will participate in the promotion during Comic-Con International. The Batwoman and Pennyworth designs appear in full below.
