The backglass carries Gottlieb's famous phrase: Amusement Pinballs, as American as Baseball and Hot Dogs! A similar playfield layout can be found on the 4-player Gottlieb's 1958 'Contest' and the 2-player Gottlieb's 1959 'Atlas'. The backglass is silkscreened with the words "Game Over" under the wing of the rocket ship and the backbox insert has a hole for a light bulb for it, but no lamp socket or wires were installed by the factory. Clearly plans were made for this game to have a Game Over relay. The match unit cuts the power to the flippers when the game is over. We previously showed a date for this game of March 28, 1958. The new date is per Gottlieb documentation.
