100+ Issue Writers (inspired by Kirkman/Invincible thread)
Always forgotten in the mix of those who've done 100+ issues of their series is Fred Perry, who's done the pop-culture American manga romp Gold Digger for Antarctic Press continuously for upwards of 200 issues (4-issue limited B&W, 50-issue B&W series plus 4 issues of Ninja High School that crossed over, the first color attempt GD: Beta one-shot, and 140-odd issues of the current color series)-- art, writing, much of the coloring when he went from B&W to color, lettering for the longest time... it was all him then, and continues to be mostly him now. In the meantime, he's also added in numerous specials and one-shots under his own name and with his own art that are in continuity. Given what he's done for that company, I might argue that he's one of the hardest-working, most underrated men in the industry.
Like I said, always forgotten. One wonders if it's because he does manga in a traditional floppy format or if it's because Antarctic is so far down the independant press ladder that they're forgotton, no matter how much of a stalwart of the industry they are. Nobody survives for 25-30 years as a small presser without at least some idea of what they're doing.
