‘Sparx’ or ‘Listening In’

‘Sparx’ card game, or ‘Listening In’, published by Chad Valley Games, Harborne, c.1910. The images show what would have been the very cutting edge of modern technology at that time. The object of the game is to obtain one complete set of cards representing a broadcasting station. The two special cards - ‘Oscillator’ & ‘K.D.K.A.’ - add extra interest to the game.
