C2E2: Chicago Comic and Entertainment Expo
Time Out says
The Chicago Comic and Entertainment Expo (C2E2 for short) turns McCormick Place into a pop-culture mecca, stocked with mountains of books and merchandise as well as chances to meet your favorite creators, actors and artists. Head to the convention floor and you'll find cosplayers and attendees mingling in a sea of vendors hawking all manner of comics, toys and memorabilia. Guests like Matt Smith (Doctor Who), William Shatner (Star Trek) and Ivy Doomkitty (Heroes of Cosplay) will be signing autographs and participating in panels throughout the weekend. And if you want to see some amazing costumes, make sure to stick around for the C2E2 Crown Championships of Cosplay on Saturday, February 29.
