The very first Hellblazer collection Original Sins is available in a new edition that includes John Constantine's appearances in Swamp Thing . This is the first of a series of new Hellblazer editions starring Vertigo's longest running antihero, John Constantine, England's chain-smoking, low-rent magus. This first collection is a loosely connected series of tales of John's early years where Constantine was at his best and at his worst, all at the same time.
