It's the image of two parallel skies, horizontal at the bottom of the image. Above the skies is the number one enclosed in a circle. In front and to the side of the number one, and partially blocking the circle that contains it, is the number five enclosed in a circle. The circle that encloses the five is slightly bigger than the other circle.
