Bob Neale's "Which Came First?" (in An Essay on Magic) is a funny routine about chickens and eggs that is illustrated with a frame-like prop that folds in an astonishing number of permutations.
The 6" x 6" prop is colored, two-sided, made of heavy paper, and scored to facilitate its folding. The prop will last for several performances, but not indefinitely.
Because of these qualities, I have had copies of the prop commercially printed; they come 10 to a pack.
Whether you want to perform Bob Neale's "Which Came First?" or merely delight in playing with his extraordinary paper toy, these props are for you!
