Delano writes anniversary 'Hellblazer'

Original Hellblazer writer Jamie Delano is returning to the title to celebrate 25 years of John Constantine.

Vertigo's official Graphic Content blog previewed pages from Hellblazer: Pandemonium.

It will be drawn by Jock - the pseudonym of British artist Mark Simpson - best known for his work on 2000 AD and The Losers.

"One of the comic book industry's iconic anti-heroes, John Constantine, the man who's literally been to hell and back travels to the only thing worse than Hades' realm - the frontlines of war," wrote Pamela Mullin on the blog.

Delano wrote the first 40 issues of Hellblazer, which debuted in 1988.

Constantine, a Liverpudlian magician of questionable morality, first appeared in Alan Moore's The Saga of the Swamp Thing in 1985.

Hellblazer: Pandemonium is released in February 2010.
