The image is a photograph of a vintage Lister Twin Diesel sign. The sign is rectangular in shape and has a white background with red and green text. The word "Lister" is written in large red letters at the top of the sign, with the word "Twin" written in smaller red letters below it. Below the word, there is a smaller text that reads "Model CE 14" and "DIESELS" in green letters. At the bottom, it reads "Manufactured 19.37". The sign appears to be placed on a grassy lawn, with a wooden stake visible in the background.
