The 2-player version is Chicago Coin's 1970 'Big Flipper' with different backglass artwork. Chicago Coin referred to the center up-post as the Ball Saver. Based on the images presented in this listing, the playfield light shields on this game exist in two different color combinations. One style is red and green while the other style is two-tone green. Two playfields of each style are pictured. We don't know why there is this difference, or if one is more common than the other. The manufacturer flyer is in black-and-white thus it cannot suggest a precedent. We previously showed Christian Marche as the artist for 'Cowboy' but without supporting information. This game is not on a list of his games that he compiled in 1992.
