Handwritten mathematical formulas and equations densely cover a deep navy ground, their white chalk-like markings creating an intricate, layered texture across the entire composition. The effect is contemplative and intellectual, evoking the visual language of a blackboard or scholar's workspace where complex thinking unfolds. 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.
