The mark consists of a fanciful gray and white gargoyle figure with a muscular body, vampire-like teeth, red eyes, devil horns and large, dark gray wings which are spread wide, sitting atop a pile of 11 skulls black and white facing different directions, including one skull at the bottom of the pile in the front just left of center with red eyes and another at the bottom of the pile just right of center with blue eyes. The gargoyle figure is superimposed on a dark gray moon nearly the size of the gargoyle and its wing-span. The wording "NOCTURNAL"appears at the top, above the gargoyle and moon, in gray letters that are outlined in white and set within an arched dark gray frame with black matting, and at the bottom the wording "MOTORCYCLE ASSOC." appears below the gargoyle and skulls in gray letters that are outlined in white and set within an arched dark gray frame with black matting.
