This design features a black and white illustration of a cartoon character, which appears to be a young boy with glasses and a mischievous expression. He is wearing a black outfit with a white collar and has a small lightning bolt on his head. Above the character, the words "Harry Potter" are written in a stylized font, and below the character, the words "On Board!" are also written in a similar style. The overall design suggests a playful and humorous take on the popular Harry Potter theme.
