This design features a graphic design with a playful and casual theme. At the center, there is a large black circle, which is a stylized representation of Mickey Mouse's iconic head. Superimposed on this black circle is a blue baseball cap with a white star on the front. The cap is positioned as if it's being worn by Mickey Mouse. Below the cap, there is a text that reads "Birthday Boy" in a playful, handwritten font. The text is in black, which contrasts with the white background of the image. The overall design is simple yet fun, with a clear theme of celebrating a birthday. The use of Mickey Mouse's head and the baseball cap suggests a lighthearted and festive atmosphere.
