July 12: comic book writer Mike Carey signing

Randy T alerts us to the fact that Mike Carey will be in town signing his new novel, and presumably his comic books as well. He's got a busy day:

WASHINGTON, DC
July 12th

1:00pm – 2:00pm Big Planet Comics, Vienna
4:00pm – 5:30pm Big Monkey Comics
7:00pm Olsson’s, Court House

I'll probably go to the Olsson's which is close to my house.

Ok, I need help here. His website says he's writing Ultimate Fantastic Four and some X-Men title, but didn't he make his name writing for Vertigo? Which trades should I pick up at Big Planet?
