The backglass carries Gottlieb's famous phrase: Amusement Pinballs, as American as Baseball and Hot Dogs! The serial numbers of this game all carry the suffix 'S' which stands for 'Silver' and does not denote a Sample game. Sample games of this period were identified with the word "SAMPLE" stamped in ink on the outside cabinet bottom. We previously showed a date for this game of August 28, 1957. The new date is per Gottlieb documentation. An Extended Play version of this game was made as Gottlieb's 1957 'Silver (Extended Play Prototype)'.
