Dick Norman presents illustrations of vintage cuffs along with drawings made from original U.S. patent papers. Take note that some of the cuffs contained were never actually produced (just patented), and that the book gives few (though representative) examples of European cuffs. Although the book is 45 yrs. old, it remains a standard for the magician/escape artist/collector, and provides the fundamentals of gimmicking cuffs and using shims to the escape artist.
