@DarkCrow,
I think you are right that its a story bord montage thts been used to summarize or "Pitch' a story.
The work is predominantly opaque projector based (today itd be a photocropped and edited study)
It seems to be about a spiritualist who can see several(future?) events in that household. Im thinking maybe its something that surrounds the civil war?
If the idea didn't sell, the pitch gets saved or tossed or filed for future sale. (sometimes a pitch campaign also comes associated with someone previously buying the rights of the story surrounding the sketches)
