The image features a white background with a black text that reads "Happy Birthday to the smartest engineer." The text is arranged in a way that the words "Happy Birthday" are at the top, followed by "to the" in the middle, and "smartest engineer" at the bottom. The word "smartest" is emphasized by being larger than the other words. Above the word "engineer," there is a small graphic of a traffic cone. The overall style of the image is simple and celebratory, with a clear message of birthday wishes for an engineer.
