In 2005 Steve Willis reprinted most (if not all) of his back catalog in editions of only five copies each. They were originally sold at the Danger Room comic book store in Olympia, Washington.
1st printing: 1982, 40 copies
2nd printing: 1982, 25 copies
The 2nd printing (see image with yellow cover) has a faint nearly-vertical line on the left side of the cover.
