Here's a link to the "Purple Pictography" series, written and pencilled by Vaughn Bode, and inked by Wrightson.

These were a feature in SWANK magazine. I've never seen the actual magazines, only seen them reprinted in Wrightson's book A LOOK BACK, published in 1980.
The purple pictography stories were also collected in the mid 1990's in a PURPLE PICTOGRAPHY one-shot comic book by Eros comics (an imprint of Fantagraphics).
