I was saddened to learn of the untimely passing of John Cassaday, one of my all-time favorite comic artists. Planetary is one of my favorite series of all time and I'm going to crack open the Absolute Editions to re-read the series in his honor.
Cassaday's work was exciting, detailed and creative. He moved seamlessly between genres- westerns, superheroes, horror, war- and that's not even counting whatever the Planetary theme was for each individual issues. His style also flowed seamlessly between panels and pages. Compare the traditional linework with the gorgous ink wash in the second panel of this page I used to own.
He'll be missed!
