A whimsical cartoon unicorn with green hair and round glasses holds a pointer stick aloft against a black background covered in mathematical equations, geometric shapes, and scientific symbols rendered in white chalk-like lines. The composition merges playful character illustration with academic visual language, creating a humorous statement about proving the impossible through rigorous logic. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
