The Selective Touch

The Royal Road to Card Magic (1948) by Fred Braue & Jean Hugard
Page 225 et seq.

Personal Comment: As with most of the tricks published by Jean Hugard this has no credits. Seems not to be the common work back then. Anyway... the trick is... well... interesting. There are quite a few tricks out there where the effect is the demonstration of a superhuman skill. I will label this as "Super Skill" from now on. Personally I find it kind of hard to get away with this as a genuine thing. If it is perceived as mere acting, then the effect is meaningless as the magician could do stronger things. But if you think you can pull this off... well, give it a shot.
