A yellow cat with black stripes is climbing on top of the question mark, vector illustration style, simple lines, flat design, red background, simple details, bright colors, cartoon character, cute and adorable, warm atmosphere. A dark blue ball lies at its feet below. The yellow kitten hangs upside down from one end to emphasize in the center of an empty space above it. It has four legs and two ears hanging straight ahead. by John Holcroft for his book cover.
