The six metal saucer shaped discs have to be interlocked to create a dice that will withstand normal handling. The advertising window card comes from a Davenport storeroom. The advertisement is from Davenport’s house magazine ‘The Demon Telegraph’, No. 118, April 1949. The puzzle came with very helpful instructions, although considerable dexterity is needed to complete the dice. The address of Samson is given as 246 Tottenham Court Road, London.
