I certainly hope you don't get attacked just because you don't happen to know the work of one particular cartoonist. That would be stupid.
One thing for which Veitch is best-liked is his run on Swamp Thing. He started out pencilling, then took over the writing as well, when Alan Moore left. Before that assignment, he contributed some uncredited art assistance to the series.
I like his Swampy, but I find a lot of his solo work to be much better. The One, The Maximortal, and Brat Pack (the latter two volumes/stories are part of a proposed trilogy, The King Hell Heroica) all deconstruct the mythology of the superhero in various ways. Pocket Universe, Rabit Eye, and Cryptic Zoo collect his comic book stories about his dreams.
All are wonderful.
But he's done a lot of other stuff. He was the artist for Alan Moore's Greyshirt, in Tomorrow Stories, and he's written some Greyshirt stories, too, including the spin-off mini-series, Indigo Sunset. He's done writing and/or art for some other tales in Moore's ABC line, here and there, as well.
He wrote a Question mini-series not too long ago, and, before that, the first twelve (or ten?) issues of the latest Aquaman series.
Back in the eighties (he's really, really, REALLY old!*), he contributed a number of sci-fi and fantasy works to Epic Illustrated -- Marvel's answer to Heavy Metal. Some in color, some black and white, some single short stories, one the multi-episode saga, Abraxas and the Earthman. He also shared art (and writing?) chores with Steve Bissette on a sci-fi/horror short story called... was it... Monkey See? A nice body of work, there.
Also from the Marvel Epic line was his full-color graphic novel, Heartburst, which I hate that I don't own. If Veitch ever reprints it, it'll probably be in black and white, and I'd really like to have it in color. I'll have to track it down somehow someday.
His brother, Tom, wrote for underground comix in the sixties and/or seventies, and I think Rick did some underground work, too. Also, correct me if I'm wrong here, Rick, but he attended, maybe graduated, the Joe Kubert school and contributed to back-up features (in just the war titles, right?) for DC series Kubert edited, as did many other Kubert students.
There are probably lots of things I'm forgetting.
*Heh, heh. Don't ban me, Rick
