I can't remember this effect. Wonder if it was from Expert Card Technique. I remember how to perform it but I think I am missing some nuances.

3 spectators pick one card each. Insert them face-up into a fan that "looks" all face-up (don't want to reveal anything here). The 3 cards end up all reversed.

I hope you can help me out with this vague description.

A Reverse Pressure Fan will set up up for what happens when they insert the cards face down into the fan.

Actually utilizes the white borders of most of the deck. The faces are seen in the top third.
Includes an effective display of the 3 cards inserted normally into the deck (front and back).

I'll let you know if I find out what book I learned this from. It's bugging me right now.
