The box measures about 10 by 10 by 10 centimetres.
According to the sticker on the front it retailed for US$ 3.79 by Sears, Roebock and Co.
The Sears company is an American institute (over the last decade fallen on hard times), with department shops across the country and a hugely popular mail order catalogue.
Inside is another box, with a Chaotic Cube.
