Continuing its Comic-Con International tradition, Warner Bros. Television has debuted limited-edition hotel key cards, this year featuring television series "Arrow," "The Flash," "Gotham," "Supergirl" and "Teen Titans Go!"
Although the "Supergirl" design isn't included among these initial images, Warner Bros. Animation delivers not one but five for "Teen Titans Go!" -- one each for Robin, Starfire, Cyborg, Raven and Beast Boy.
What's more, the "Teen Titan Go!" cards will include a special QR code that will allow guests to watch a free episode of the animated series.
Nearly 40,000 branded key cards will be distributed among 30 participating Comic-Con hotels.
Comic-Con International will be held July 8-12 in San Diego.
