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. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
