I do have a few bits of author memorabilia – a small model of one of the Burgess Shale critters which once belonged to Doc Smith is probably the most interesting one – but I don’t feel a great need for furnishings with that kind of provenance.
On the other hand, I do need to build or buy something similar for one of the bedrooms in my house. (Probably build, given the prices stores want for plywood boxes.)
