A whimsical algebraic equation unfolds across a cream ground, with zebras substituted playfully into each line of mathematical notation to transform abstract symbols into living creatures. The monochromatic pen illustration progresses from a formal formula at top through increasingly chaotic simplifications, culminating in three striped zebras standing side by side as the final punchline. 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.
