The design features a bold silhouette of a stag's head, rendered in solid black against a stark white background. The stag's antlers are prominent and detailed, extending outward and upward with multiple points. Below the stag, the phrase "Expecto Patronum" is displayed in a serif font, with the words "Expecto" and "Patronum" written in a larger size. The text is centered and appears to be in a deep black color, providing a strong contrast to the white background. The overall design conveys a sense of power and elegance, with the imagery and text suggesting a connection to themes of magic and protection.
