The mark consists of a first line that extends diagonally downward from right to left connecting to a second line extending horizontally to the right, and then connecting to a third line extending diagonally upward from right to left, but not connecting to the starting point of the first line, forming the partial outline of a first triangle. The terminus of the third line connects with a fourth line that extends diagonally downward from right to left and extends through the second line, creating a break in the second line, and forming a smaller second triangle within the larger, partial outline of the first triangle. The word "AASPIR" appears directly below the two triangles.
