“Houdini and his wife Bess did not ever have children. Instead they showered their affection on each other, and on the collection of pets they built up. Houdini particularly treasured this photo of him holding several of his beloved pets.”
This is a deceptive quickie that has several hidden layers. It started life as little more than a sight gag, but gradually Wayne has added to it to give you a multi-layered, close-up, comedy prediction effect.
Houdini believed there was a correlation between a calendar (diary) and a deck of cards. This effect uses a standard deck of cards and a diary that does all the work for you. There is no memory work, no algorithms to remember, nothing. It’s pretty much a self working trick!
