Not a particularly rare book, but this copy is inscribed to Roger Zelazny. This was one of a group of books formerly owned by Zelazny, and individually sold by his heirs shortly after his death. I ended up with 40 such science fiction books (most inscribed to him), whilst a good friend of mine got a large grouping of non-fiction, apparently used by Zelazny for reference. I thought it rather a shame the collection was broken up like that, and was pleased to be able to keep so many of them together. Unfortunately I could not afford all that were available.
