Hurst, it's worth a tenner, no more. It's just a marketing brochure with pictures and text. Don't really know what the big deal is, except I guess it's somewhat rare and the subject matter is very interesting to some of us. But 1600 gbp? You'd have to be nuts. Maybe the auction was rigged to help the sale of the second one--it sounds fishy to me.
Incidentally, I have the whole thing scanned in. You want? :-)
