Chuck Hickok has one with 50 postcards from the states of US. You split the pack into several smaller pacs and distribute among the audience. One (and later several) of the audience is to pick one postcard (of 10) and put into your stack of 50. You can after briefly scanning though the pack identify the added postcard. Continues into several new steps.
ok may have to buy this one!!!!! i have barrie richardsons steven kings sized book to get though, and there is a memory effect in that. i sent ages to learn it and get it perfect but when i do it on people, their like " oh whats the point in that"!!!!!! I then explain if they took the time to master what i can do then they too will be able to pass exams or other memory feats with ease, and that normally shuts em up
all those that believe in telekinesis raise my right hand!!!
