Charles Hopkins wrote this booklet in 1940, and for almost 70 years it has been essential reading for serious cardworkers.  Hopkins deals with those times when things do not always go as planned, but rather than simply admitting failure and hoping the next trick will re-gain the respect of your audience, Hopkins discusses about sixty ideas for concluding every card trick you start SUCCESSFULLY!   How to get OUT of a jam, overcome difficult CHALLENGES, and what PRECAUTIONS to take to minimize these problems.  Even if you are perfect (like me) and never make misteaks...I mean, mistakes, you can get lots of ideas for interesting card revelations from this book -- yes, you can plan ahead and use these outs as part of an impressive planned routine.  This is a later, undated reprint, by Tannens or maybe D. Robbins.  Mint condition.
