Ah, 1972. I was in the Army, but had lots of down time, hanging out with my hippy friends, some of them in the Army too. It's not just long hair that makes a hippy. It's an attitude, and so many of my Army buddies were drafted (forced) into the armed forces and there was just as much dope and stuff in the military as out.
For short breaks, the underground comics were our readings of choice, and several of us artsy types tried our hand at drawing the underground style. Dave Sheridan and Fred Schrier were our idols for that kind of work. Crumb was good, but seemed a bit brown shoe for our efforts to emulate. Shelton was good too, but didn't seem stoned enough, maybe he seemed too vaudevillian and slapstick.
Whereas Sheridan and Schrier seemed like they were corresponding from another dimension. Here, Sheridan has drawn some phunny money that was used for promotional handouts, and in a pinch could be used to roll your own smokes, this one surviving somehow.
Above and below, Dave Sheridan's front and back of the phunny money.
