Corkscrew for Collectors By Bernard M Watney & Homer D Babbidge
Second Edition 1983
As the original book on corkscrews, this book is revered by collectors. A must have for all collectors. It has both color and B&W pictures of some rare pieces, which have disappeared into collections. This is worth it just for the Appendix - The ritual of opening and decanting vintage port with the aid of a corkscrew.
