Snyder's Marbo-Card

A small walnut box with mahogany accents is displayed as well as a steel ball and a standard playing card. The box has a hole through the lid as well as the base of the box. It is noted that if the playing card is placed within the box and the lid closed it would be impossible for an object to pass through the box via the two holes. The steel ball is placed on the top of the box and rolled from side and finally drops out the bottom of the box! The card is immediately seen through the holes in the box and no clue of trickery is evident. The lid is removed, card again examined as well as the box. Includes instructions. Very good condition.
