Another rare find, pre-dating the first issue hardback, is a proof cover design for Bloomsbury, dated June 1997.
This is a scarce proof sheet of the proposed illustrated wrappers, which would have accompanied one of 200 uncorrected, pre-publication copies of the book. A rare survivor with considerable variations from the final published version, it sold for £9,000.
Jim Spencer, books expert at Hansons, said: "It was a thrilling afternoon in the saleroom. People were joining us online from all over the world.
"Some of the bidding battles were slow-burning, really tense, gradually building up into a frenzy between determined collectors.
"I receive countless enquiries every week, but I feel like I really get to know our vendors, I learn their stories and share them with the world, we enjoy chatting, so it's quite a bit of pressure hoping things will spark interest for them, it's fortune-telling really, and so I feel really excited for them when things are racing away. Charles was, as always, a showman on the rostrum, fizzing with energy and enthusiasm and excitement."
