If you are looking for a book full of quick mental magic gags, this isn't very good. All the tricks in this book require either A) Advanced skills in slight of hand (palming, quick switches, etc) or B) A gimmicked apparatus. It isn't as easy as amazing your buddies at a party with some mind reading tricks. These are for more advanced magicians. It was also written in 1944.
That being said, it is a very interesting look into how some of this stuff is (or was) accomplished. I have seen several of these tricks used before and wondered how they were pulled off, now I know.
If you are a magician with basic skills in slight of hand, palming, and switching, then you will probably find some cool additions to your performance here.
If you are looking for some basic stuff to baffle your friends with, this is not the right book for you.
