I have a copy of A.O Spare's Book of Pleasure, one of the hardbound numbered ones from 1975. I bought it a number of years ago on eBay. The book is in good condition, but the dust jacket has some tears in it. I found archival repair tape at http://www.vintagepaper.co.uk/. This site has all kinds of bookbinding and repair materials and tools. I just wanted to give them a blatant plug here.
