This is a modern example purchased from The British Museum shop in 2017. It was said to be painted by a Chinese painter. The stopper is probably agate. Both sides of the bottle are shown in the photographs. These objects are often referred to as ‘impossible objects’ because it is hard to understand how such detailed painting can be achieved on the inside of the bottle.

Each of the five boxes requires two moves to open it. Each box has a different animal design on the lid. On the inside of the lid of the outer box ODAWARA MADE IN JAPAN and a symbol are stamped in ink.

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.

Cut the postcard into 3 pieces. Where does the 16th card go when the position of the two lower pieces are reversed? The postcard advertises Martinka & Co., a magic shop in New York City.

The puzzle is to open the piece. It advertises M.C.L. AND REPETITION LTD. The outer surface also includes the words BRITISH ALUMINIUM BA-35. This will be the alloy type from which the puzzle is machined.
