I was discussing this with a friend & we talked about what was around then. R Crumb drew the 'Fabulous Furry Freak Bros' and 'Fat Freddy's Cat' - funny stuff!
There was another artist who drew the "Keep On Truckin' icon, but I can't recall his name. He was heavily into the acid culture while Crumb was more in tune with the no-brain pot heads. Still funny comix, though.
My favorite was Vaugh Bode' who drew the 'Deadbone Mountain' series for Penthouse. It was popular for its ironic outlook on the war and sympathy for the lowly grunt. It was very dark humor, though & I think that's why I liked it. Maybe I should say EXTREMELY dark humor.
An acquired taste in any case.
I recall seeing a lot of one liners from his comix engraved on Zippo lighters. Nearly every grunt carried a Zippo even if they did not smoke... very useful for burning off leeches... lighting the blue tri-oxane tabs to heat C-rats... igniting safety fuse when blowing a mine in place...
1001 uses for a Zippo!!!
Anybody else enjoy underground comix in those years? SW
