On the first Saturday in May, thousands of comic book stores give away a free comic book to anyone that walks in their door, while supplies last. Bucktown's Challengers Comics + Conversation at 1845 N. Western Ave. will be participating in the holiday from 11 a.m. to 5 p.m. Saturday.

In addition to a free comic book, local authors Jamal Igle will be on hand to sign "Molly Dancer" and Chris "Elio" Eliopoulos will sign "Mr. Puzzle."
