Unnamed Trick by Bro. John Hamman

The Secrets of Brother John Hamman by Richard Kaufman and Alan Greenberg
Page 18 et seq.

Personal Comment: No kidding, the name of the trick is actually the main method that is being used. It is bold, but interestingly still deceptive. When I did this for real people I changed the grip on the cards. Doing an Elmsley while holding the deck is a bit too demanding for my hands. They are not that huge. So right now I am going into Brother John Hamman's work. I may have to adjust the technique a few times to still do the effect. Please forgive me for that. The above video is excuse enough to cheat.

Difficulty 4/5
