I am a big fan of Laurence Campbell's art on B.P.R.D. Hell on Earth. When he recently released his sketchbook of covers I had to get one. I asked if he had any of the original artwork for sale. These are the 2 covers I bought from him.
B.P.R.D. Hell on Earth #134: The emergence of Johann Kraus wearing the Sledgehammer Vril energy suit. How awesome is that!
