2.25" with additional text "'Tween The Eyes." In 1986 when the first Lazer Maze in the United States opened at the Sherman Oaks Galleria on December 18 the manager Ben Platt described the concept as "These Are Participatory, Walk-Through Human-Action Video Games." The game heralded a shift away from electronic videogames to the new age of player-interactive games. Button curl has text that includes the abbreviation for the state of California although the additional text is below the metal back and not readable. The button's pin on the back caused a tiny and a somewhat larger pair of bumps on the front surface with the larger visible and noticeable to the touch but otherwise the button is Essentially Mint as made. From the Marshall Levin Collection. Only example we've seen. Comes with Hake's COA.
