The mark consists of two concentric brown and white rectangles tilted to the left and resting on the bottom pointed left edge, with each rectangle divided into two triangles, one solid brown triangle forming the left side and part of the bottom side of the rectangles, and the other white triangles forming the right sides, top sides and part of the bottom sides of the rectangles; in the larger rectangle, the brown triangle is solid brown, and the white triangle is outlined in brown with a gap at the top portion where the vertical leg meets the hypotenuse on the bottom edge of the rectangle; the smaller rectangle is outlined in brown on the right and top sides, and in white on the left and bottom sides, enclosing a smaller solid brown triangle on the left outlined on the vertical and horizontal sizes in white, and an incomplete white triangle on the right and top sides of the rectangle, with incomplete sides at both ends of the triangle which is outlined in brown on the two straight sides; nine shaded separate ovals that fade from light gray to black, in the combined shape of a rectangle emerge from the center to the upper right corner of the larger rectangle, extending upward and diagonally to the right of the rectangle.
