This is a cool way to advertise for yourself and make the volunteers in your show happy at the same time.
This is a Magician’s Assistant Certificate that rolls up into a wand.
You may produce the wand using any of your favorite production methods (or just openly bring it out) and then hand it out to your volunteer helper.
When they open it they will see a beautiful certificate.
These are vintage new old stock from an old magic estate purchase.
Very nicely produced!
