The mark consists of the configuration of the front view of a bridge on a guitar. The mark begins with a horizontal line curving gently downward toward the middle and then back up to each end. In the middle, the lines curve upwardly to form a slight point. Continuing downward from each side of the horizontally curved line are vertical lines gently curving inward to that they are closer together near the bottom portion of the mark than they are from the top portion. Connecting the two sides of the mark is another horizontally extended line which is not as long as the smoothly gently curved top line. This bottom line comes inward from the vertical sides rising slightly and then curving downward to form two very slight points. From the points, the line curves slightly upward and then gently downward where it retains a slight curve downward and inward until it meets in the middle. There are also two straight vertical lines which bisect the mark about ¼ of the length of the mark set inward from each end. The vertical lines stop about ¾ of the way from the bottom of the mark where two vertical lines begin from the bottom of the mark and arch slightly upward and inward from the bottom of the mark to connect with these two vertical lines and then continue curving gently upward and then horizontally to meet in the center of the mark.
