Comic-Con is giving out free collector's items this year to all guests in the convention center.
For the first time, every guest receives a badge box on the 2nd floor of the convention center. Inside the box is a Comic-Con 2017 collector pin.
Every fan also gets a bag that can double as a backpack. Each of the bags have different television and movie themes such as The Flash, The Big Bang Theory and Supergirl.
On the outside corner of the bag is another souvenir pin of Batman, Superman, and other superheroes.
Fans were already trying to trade pins and bags Friday.
"I would love to trade with someone," said Emily McFarland, 15. "That would be so cool."
