The mark consists of three identically sized, parallel rectangles with the rectangle on the left being positioned the highest and the rectangle in the middle being positioned the lowest; each rectangle is positioned directly above and having the same width as a trapezoidal pillar positioned beneath each rectangle; each trapezoidal pillar has two right angles on top and is evenly spaced from the corresponding rectangle above them; the central trapezoidal pillar merges at the bottom with a curved swoosh or slash; the left and right trapezoidal pillar do not merge with the swoosh; the swoosh is thicker in the middle than the ends; the ends of the swoosh curve upward toward the rectangles; the width of the swoosh, including the each end of the swoosh, is wider than all three rectangles and their trapezoidal pillars; the swoosh is tilted so that the right side is higher than the left side; the right side of the swoosh terminates at about the same height as a mid-point of the right rectangle; the left side of the swoosh terminates at about the same height as the bottom of the center rectangle.
