This design features a red and white rectangular sign with rounded corners. The sign has a bold red border and a white background. The text on the sign is in a cursive font, with the words "DO NOT OPEN" written in large, bold red letters at the top. Below this, in a smaller, but still prominent red font, the words "UNTIL CHRISTMAS" are written. The overall style of the image is graphic and appears to be a digital or printed sign.
