The image is a photograph of a stone sign in a grassy area. The sign is rectangular in shape and has a white background with black text. The text on the sign reads "Areniscas Estefaniense de Villablino" which translates to "Carbonifero" in English. Below the text, there is a barcode and a logo of a bird. The stone appears to be old and weathered, with some cracks and chips in the surface. The grass around the sign is green and well-maintained.
