Dancing Lady was the first pinball machine to have these features: 1) decagon score reels 2) score card holder with ball-in-play and game-over lights 3) playfield carousel roto-targets Dancing Lady was the first Gottlieb machine to adopt these features already in use by other manufacturers: 1) triple coin chutes 2) all-stainless steel front molding (lock-down bar) 3) automatic ball-lift, a feature already in use by Bally, Chicago Coin, and Williams. Keeney also used it right up to their last game Keeney's 1964 'Arrowhead' in August 1964. Sample games, like the one shown in the flyer, had a slightly shorter backbox and backglass than the production games. Additionally, the sample backglass had different colors around the score reels of each player, whereas the production backglass used a black color for all players. Most of the artwork appears to have been redrawn in the production glass. The A-B-C-D playfield outlane artwork of the sample game were also changed and recolored for the production game.
