The image is a photograph of a sign in a park or garden. The sign is rectangular in shape and has a black frame. The background of the sign is a light beige color. On the right side of the image, there is a text written in black ink that reads "Signs of an Underground River". The text is written in a cursive font and is centered on the sign. Below the text, there are two smaller text boxes with the same text. The text boxes are slightly blurred, but it appears to be made of wood or metal. The image is taken from a slightly elevated angle, looking down on the text boxes.
