I went to see Bill Willingham, the writer of Fables, speak at the Brooklyn Book Fair two summers ago, and he complained that his editors at Vertigo strongly suggested including naked characters in the stories, because Vertigo is the mature readers line, and sex sells. After Fables gained more commercial and critical acclaim, he was able to fend off those suggestions, but said he still gets them every so often.
I highly recommend Fables, especially the issues after Mark Buckingham takes over as the artist. The first book has some fairly gratuitous sex scenes, but after that, there's nothing in there that would make you embarrassed to read it in public (with the exception of the recently released Werewolves of the Heartland). But the stories are mature, and not in the mature equals T&A and violence sense. It deals with geopolitical issues, marriage and family.
What's your minimum value threshold for sending a book to CGC for grading? I understand getting a high grade copy of Walking Dead 1 graded, but I don't understand when people get just off the rack comics like Marvel NOW! Uncanny X-Men 1 graded.
Brainiac is such an iconic villain that not having him in the set seems wrong to me.
It looks like most people agree, since he's leading by a very wide margin. Personally, I'd like to see Sinestro in the set. He would have received my vote. I'd cut Deadshot to put both Sinestro and Brainiac in.
