The backglass pictured in the manufacturer's flyer names the city of Buenos Aires as one of the "Olympic Cities". At some point in production, this city name was changed on the backglass to read "Caracas". We also notice the right outlane will be labeled as either "Buenos Aires" or "Caracas". Owners may find that their schematic has the name "Caracas" ink-stamped over the name "Buenos Aires". We don't know the reason for this change, and the "Buenos Aires" version may have been on sample games only. Both versions are pictured on games in this listing. One game has a "Caracas" backglass and a "Buenos Aires" playfield.
