Cover Art of Hellblazer (1988) #61.
*There are those who regard John Constantine as a friend, never seeing - or never wanting to see - the ghosts of other "friends" who did him favors and died for it. Favors count for much in his friendships, because the things that Constantine must do are usually too big for him to do alone; because when the devil himself is on your tail, it's handy to have something to drop in his path; and because - perhaps most crucially - the dead friends keep the flame of guilt burning in his eyes. *Source: Back of card
