See-Thru Block Box - Magic House of Babcock

Description

EFFECT:
A block is placed into a double-sided box, similar to a die box. The box is tipped back and forth and the block is heard to slide from end to end. When the box is finally opened, the block has vanished.  In this case, when the block is shown to have vanished, both front and top doors are opened, the back is opened, and the two end panels are lifted out. This leaves a skeleton framework of a box which may be shown from all sides.
Like a die box, this box also has a sliding weight for the standard sucker effect.
This is the smaller version of the effect in which the size of the block is 2.25 x 2.25 x 2.25 inches.
Complete with original instructions.
The Magic House of Babcock is known for its quality, collectible apparatus, and this is an unused item from a collection.
