Steve Kordek said at an Expo 2009 seminar that Gottlieb notified him that he could not use the name 'Add-A-Ball' for this game. Reportedly, only a small quantity of this game was made before it's name was changed to Williams' 1961 'Skill-Ball'. Christian Marche is listed in other pinball resources as the artist for this game. In an interview appearing in The Pinball Compendium 1970-1981, he states he moved to the USA in 1964 where he started work at Advertising Posters. Therefore, we have removed his name as the artist for this 1961 game.
