I found some more underground, small print run graphic art comic that could be construed as comix, but that could be a stretch, seeing as how the subject matter isn't exactly comix-themed:
It's a collection of The Cave Man Speaks comics from Guarino and Westerfield, who I believe published originally online.
It also collects a longer form silent piece starring the main caveman from the cover in a bit of a darker role.
All in all, its pretty good, and I like supporting the fringes of the fringe. I am inspired to check out their other, far longer collaborations: "Amboy, Pop. 5" and "Moses", both of which are stationed at a local indie record store.
