Here's something from the Post Weekend section from 1996 for Friday the Thirteenth. I also ran it last year, but almost too late for Friday 13th, so here it is early which should give you time to prepare. The cover was watercolor, one of the first large ones I tried. The inside drawings were pen & ink with colored pencil and pastel blotted with Liquin (a weird mix but it reproduces well enough on newsprint). I wish I'd spent more time on the demons unrolling a calendar on the first page. See also here.
