A friend of mine just lent me a book called "Tour of the Universe" by Robert Holdstock and Malcolm Edwards. It is presented as the scrapbook of a lucky human couple in the future who win a lottery and receive tickets to a tour of the universe. The book is lavishly illustrated and includes ticket stubs, hotel brochures, starliner publications and all the ephemera collected on your average tour of the universe.
I intend to scan in several of the illustrations, but let me start off with a cross-sectional map of one small part of Tombworld, a tourist destination planet that was used for millions of years in the past by spacefaring species from many different planets to inter the remains of powerful individuals. The surface of the planet is hidden beneath kilometers of ruins, but recent award winning work by a corporation holding tourism rights showed that sunshafts designed to bring sunlight down onto the masks of the sleeping kings from the earliest levels were incorporated into the designs of later tomb builders and provide uninterrupted vertical access; hundreds of sunshafts have been identified granting access to all layers of the mausoleums.
I am totally stealing this map:
