The image shows a blue and white signboard with the text "Freiwasserzone" and "Unterwasserplanzen-Zone" written in German. The signboard is located on a wooden dock with a body of water in the background. On the left side of the signboard, there is an illustration of a tree with green leaves and a blue sky. The text on the right side is written in white and black. Below the illustration, there are two smaller illustrations of different types of plants and trees. The image appears to be taken from a low angle, looking up at the sign board.
