Every month along with the ComicTom101 Exclusives we randomly add Hot Keys and Big Books like Giant Size X-Men #1, Hulk #181, and more. One lucky Mail Call Member gets the surprise of getting a grail book for the cost of the Mystery Mail Call. We do double blind sorting so there is no way we know who gets the book. Check out these members who found the Hot Key books and shared with the Comic Fam on their social media!
