One co-created 30 Days Of Night. The other co-created Swamp Thing.
And now together they are creating Frankenstein Alive, Alive! for IDW, from Steve Niles and Bernie Wrightson.
Wrightson of course has good form, illustrating the Mary Shelley novel over a period of seven years. I think we can all expect to see this displayed at Tr!ckster and San Diego Comic Con 2011.
