As is tradition, Warner Bros. sponsors the big bags Comic Con attendees receives upon arrival at the San Diego Convention Center every summer. This year, the TV studio is promoting cult-fav shows like The Big Bang Theory, The Following, Revolution, Arrow, Supernatural, and Teen Titans Go!. The bags double as backpacks with straps, and a small detachable cape is provided just in case you forget your branded cosplay. Over 130,000 bags are being produced for Comic Con, so there should be plenty to go around. Check ’em out in the gallery below. Comic Con begins Wednesday, July 17 with Preview Night and runs through Sunday the 21st.
