London, Gollancz, 1953. Hardback first edition and first impression. Very good book in a good jacket. The book has an owner's inscription, and a little spotting to the front pastedown. A little grubbiness to top of boards. Jacket is good only, mostly complete but with a few chips and tear, most notable is the upper spine tip which has a little loss, including the word invisible. Price-clipped, spine discoloured. Tape ghosts to inside of the jacket.
