This design features a graphic design with a white background. At the center, there is a large, stylized text that reads "LITTLE SISTER BIGGEST FAN." The text is arranged in a playful manner, with the words "LITTLE SISTER" in a larger font size than "BIGGEST FAN."

The baseball and heart are both in a simplistic, cartoonish style, with the baseball being a solid color and the heart being a combination of green and yellow. The overall style of the image is casual and fun, with a clear focus on the theme of baseball and the relationship between a little sister and her big sister. The design is likely intended for a fan or a sibling who is a fan of baseball.
