I mentioned this in Food or Comics? yesterday, but thought it was worth mentioning again (esp. since Vertigo posted a preview on their blog today) ... although it was originally solicited with Jill Thompson on art, the Madame Xanadu tale in this year's House of Mystery Halloween Annual is actually Matt Wagner and King City creator Brandon Graham. It's kind of like finding out the house next door isn't handing out candy this year (boo!), but they did make popcorn balls (yay!).
Wagner and Graham join Matthew Sturges, Peter Milligan, Luca Rossi, Mike Carey, Peter Gross and more in contributing to the anthology. It arrives in shops today.
