Two flat buttons.

One button has a smooth edge. On a smooth background is a fouled anchor with the rope tied to the ring at the top. It goes under the left-hand stock, then under the shank to the right, then back under the shank to the left, under the left-hand fluke, curls under the crown and then under the right-hand arm.
