In a press release from Warner Bros. and DC Entertainment: "If you’re going to San Diego Comic-Con, you’ll be walking away with plenty of swag. But if you’re worrying about carrying it around the convention floor—don’t. After all, you just might have a super hero to carry it for you.
Yes, for the sixth year running, Warner Bros. will be providing the official bag of Comic-Con, which you’ll get when you grab your badge at the show. The bags will once again double as backpacks and feature the all new 2015 Comic-Con official design on one side and one of thirteen different designs on the other. Those designs will each highlight a different Warner Bros. TV series, with nine of them devoted to DC Entertainment properties."
