The mark consists of the stylized letters "J", "S", and "K", with the "S" and "K" being attached at the bottom portion of both letters and the letter "J" appearing above and in-between the "S" and "K" with the bottom hook of the "J" fitting tightly into the empty space at the top of the "S". In the background is the left half of a semi-circle composed of many concentric circles. The semi-circle is brighter toward the center, which is at the right of the image, and fades out toward the circle's perimeter.
