If there must be a monument, blank might look good. If Gary has a tool to engrave into it, a slate slab would be ideal. Like the old ones falling over in cemeteries from 1600s. Will need to sort this out, but I'll put this here for now to force myself to think it through. If I'm gone before I can, then Rae may have some good ideas.
