Labeled in the directory name as a collation. And there's actually one photo that fits a collation (it's stapling, not collating).

The thickness of the sets of pages, and the number of them, are compatible with a Minneapa collation. I haven't checked to see if I can match that cover (which we can't see too well) anywhere near the fall of 1988. But that could be a lot of covers to look over. (Many are colored and could be very easily ruled out.)

But it could be something else of course.

It's in some fannish household. Anybody have a clue which one? Cross-checking that against Minn-StF meetings and Minneapa collations might help (but 1988, which it might be near, is long enough ago that our records aren't too good).
