It’s a backpack. It’s a cape. It’s a backpack with a cape! Warner Bros. Entertainment will once again sponsor the official bag at Comic-Con International: San Diego 2013, to be distributed to fans when checking in at the Con, the Studio announced today. This marks the fourth year that Warner Bros. and Comic-Con have joined forces to produce and distribute what Entertainment Weekly once called the convention’s “ubiquitous accessory,” ensuring that attendees have a unique keepsake from the world’s leading pop culture convention. Plus, for fans in San Diego who forgot their costumes, the “must-have” bag (according to Deadline Hollywood) not only lets attendees tote copious amounts of swag, but they can also flaunt their super hero side with the backpack’s detachable cape!
