The image features a black and white sign with the words "Happy Birthday" written in a cursive, elegant font. The sign is adorned with two bow-shaped decorations at the top, adding a festive touch. The sign is mounted on a vertical pole, which is also black, providing a stark contrast against the white background. The simplicity of the design and the clear, bold text make the message of the sign immediately recognizable. The absence of color focuses attention on the message, emphasizing the sentiment of the birthday greeting.
