I recently found a small stash of my old self-published minicomix, including this one from 1988.
Alter(c)ations was one of my "secret" publications. These were printed in editions of 50 copies and were never advertised or sold. I gave them away to friends or sometimes threw them in with an order of other comix.
The images were made from magazine pages (and one "McHale's Navy" bubblegum card). I defaced the source material with white-out, X-acto blades, correction tape and ink. That's a little rubber stamp image of Hedorah (the Smog Monster) in the corner of the next-to-last page, and it looks like the background on the final page is an enlarged photocopy of a Pep Boys ad.
