The metal side rails shown in some pictures were an after-factory option for operators. They fit over the existing wood rails and were nailed to the sides of the cabinet. The backglass carries Gottlieb's famous phrase: Amusement Pinballs, as American as Baseball and Hot Dogs! Included in this listing is a backglass that does not show the second half of that phrase: American as Baseball and Hot Dogs!. We don't know the reason for this omission or how many were made like this. Also included in this listing is a silkscreened backglass made in the style of artist Roy Parker and appears completely redrawn when compared to the production backglass. Many details such as facial features, horse musculature, and racetrack dust are not as pronounced. It is lacking the slogan "Amusement Pinballs as American as Baseball and Hot Dogs!". Notably, the Gottlieb logo lacks the postal zone code that Gottlieb had used as early as 1957. We do not know if this "alternate" glass was a pre-production presention by Parker or if it was a later copy made by someone else.
