This is 54 year old game is something a collector would love to have in their collection. It is brand new therefore never been used nor has the box ever been opened. The reason I say this, is, back in the day the stores would tie a string around the game boxes. The box is worn from being stored in different areas of my mother's house. The tethered pendulum ball flips the blocks from X to O or vice versa. Don Adams was the star of 'Get Smart' TV show who was the game host. Accepting cash only. Willing to negotiate price.
