The mark consists of the capital letters "GBK" followed by the lowercase letters "intl." with a space in between. Above the letters are five horizontal lines that are about twice the length of the group of letters and centered on the letters. The third, or middle, line is the thickest of the group and the first and fifth line are about half the thickness of the third line and the second and fourth lines are very thin. The spacing between each line is the same width as the second and fourth lines. There are also three horizontal lines below the group of letters that are the same length as the lines above and centered on the letters. The first and third lines aret he thickest and the second, or middle, line is half the width of the first and third. The space between the lines is the same as the group of lines above the letters. Each group of lines is spaced a distance about half the height of the letters away from the letters.
