For those of you who have never heard of ElfQuest, here's a very brief synopsis from the site:
Elfquest (the original series): 20 "magazine-sized" comic book issues published in black and white from 1978 to 1984. These tell the story of Cutter, his tribe the Wolfriders, and their quest to find and unite other groups of elves against the threat of humans, trolls, and other assorted nasties.
The original series was written and drawn by Wendy and Richard Pini, but apparently other authors and artists have expanded the series.
If you're thinking of reading them, be aware that they're adult comics, with a fair amount of sex either shown or implied. Personally I loved the artwork and thought the stories were pretty cool. I even did a bit of fan art for this, though not as much as I'd wanted (I'd had plans to do all of the major characters and only managed to do two of them - maybe something else to do next year?).
You can find the comics gallery here with several more series than existed when last I picked up a volume (I read The Original Quest, Siege at Blue Mountain and, I believe the start of Kings of the Broken Wheel). If you want to know what order to read the books in, here's a guideline.
