The image shows a small rectangular sign attached to a gray concrete wall. The sign is rectangular in shape and has a yellow background with black text. The text reads "MAILS LETTERS" in large, bold letters. Below the text, there is an illustration of an envelope with an "@ symbol on it. The envelope is outlined in black and the text is written in a cursive font. The wall appears to be old and weathered, with cracks and peeling paint visible on the surface.
