Thumb fun Sid Lorraine and Devin Knight

This was one of Sid Lorraine’s most popular tricks. It has been off the market for more than 40 years. Devin Knight obtained permission from the Abbott Magic Company to release this again and to update the original directions. How good is this effect? Well, it was one of the late Doug Henning’s favorite tricks and was personally taught to him by Sid. Doug Henning used it everywhere, including in some of his touring stage shows, showing it on a big screen behind him.

A playing card is selected and kept a secret from the performer. The performer shows five small white cards blank on both sides, the size is roughly 1.5 x 2.5. He cleanly removes a card and shows it to be blank on both sides (no double-lift).



The performer shows there is nothing on his thumb and presses it against the blank card, when he lifts his thumb, there is seen to be a black thumbprint with a small replica of the chosen card inside the thumbprint. One of the most novel and commercial card revelations ever invented and a favorite of many professional magicians. Everything can be examined. You can repeat the effect later and have a different card appear. Appeals to all ages. You are not limited to playing cards, you can make numbers, ESP symbols or even the person’s initials appear within the thumbprint. You can leave the thumbprint with the spectator to show to others.



This effect comes with Sid’s complete directions updated by Devin Knight. A highly sought after effect by collectors that is now available again. The effect looks so good you will almost fool yourself. Learn to do it in five minutes.

“I really do think this gem is something that many magicians will find as a ‘keeper’ as they perform it and realize the wonderful effect it has on an audience. You have revived an exceptional piece of magic for many to enjoy! I’m impressed and very happy that you’ve gone through all that you have to make this available again.”
