As a self-proclaimed "geeky shopping extravaganza," the Calgary Expo Holiday Market celebrates the holiday season with two full days of comic books, collectibles, cosplay, and more. Inside, attendees—who are encouraged to wear their costumes—can browse aisle after aisle of merchandise, just as they would at an old-school comic show. They can also explore artist alley, where artists showcase and sell their work and mingle with their fans.
