Draw a picture of a rabbit with chalk on a metal board. Show the rabbit you drew and place it into the slot into the box. Tell them this is a 3-D box machine. They can see inside the box & the rabbit drawing. Close the front door and remove the drawing, now when the front door is opened, there is a real rabbit inside, open top door and remove it. A clever way to produce a rabbit!
CONDITION: VG (the box does not look used as all, but has some chips of paint on the top front and sides, as seen in the photographs. Nothing terrible, but peeled off most likely from age. This comes with original Tannen instructions, but for an earlier model that you put together. The routine is the same however)
