Kev Nowlan graduates to full B.P.R.D. covers. The guy just doesn't do bad work. I'd guess it's either from a Mignola rough, or just a very Mignola-esque design.
Speaking of Mignola: here's the cover to THE WILD HUNT #2. I starting to reckon Mignola doesn't use ink anymore: he just bashes this stuff out straight into a copper plate with a hammer and chisel. Glorious.
