Mr. Suydam's probably best known for his artwork which can be found gracing dozens of covers featuring the MARVEL ZOMBIES characters.
While portions of the project were displayed at various times, all 100 Hulk (2008) #1 Covers were displayed together in the "Green Room" at Wizard World Chicago 2008.
