The Add-a-ball version of this game is Gottlieb's 1970 'Card Trix'. The backglass shows a college dorm room with pennants on the wall and a study desk. It also shows the name of this game as 'Flip a Card' (no hyphens) but the game is always spelled 'Flip-A-Card' in the manufacturer literature. Pictured in this listing are two playfields stripped of their parts in order to best show a subtle factory color difference between them. One playfield has a light beige color, while the other playfield has white, on the top "K" rollovers worth 300 points, in the lower pop bumper circle, and in the playfield arrows that point to the targets. We do not know the reason for this difference, or how many games were made of each color. We previously showed a date for this game of March 1970. The new date is per Gottlieb documentation.
