If you’ve ever been to a concert before, you may have recieved a program. It’s basically a small booklet that contains the list of music that will be played.
Consider having a program for your magic show. Souveniers are always fun and it helps the audience remember the show. It’s also a good way to provide historical context behind the magic we do without taking up any show time.
If you’re worried about people looking up the methods to your tricks, don’t be. You should be more worried that they’ll forget everything and all the time and effort you’ve invested into this accursed craft is for nought and your life has been nothing more than a brief flash of light in a dark galaxy.
