The Piccadilly firm Giuliano was commissioned to create a series of gilded rooks in 1897, to commemorate a chess match played between the House of Commons in Great Britain and the House of Representatives in the United States.
Five members from each house were selected to play the game, with moves being communicated via transatlantic cable over two days. The event was to demonstrate the extraordinary capabilities of this new technology and each rook was mounted with a slice taken from the transatlantic cable. The match ended in a draw.
Another example can be found in the permanent collection of the Victoria and Albert Museum (M.8-2011). It is not know exactly how many were made, but is seems likely that each of the players received one.
