Each poster was stamped with unique combinations of symbols hidden under scratch-off ink. Some posters had prize-winning combinations, which were based on Jack White’s song lyrics. For example, in the song The Black Bat Licorice he sings “Good for the needy, like Nietzsche, Freud, and Horus”, so revealing portraits of those men in that order would win fans a prize. Every poster purchase also included a commemorative coin that matches the coins illustrated on the poster and which could be used for scratching off the slot machine windows.
