White mathematical formulas and equations densely cover a charcoal gray ground, creating an all-over pattern of scientific notation and symbolic language rendered in a handwritten style. The composition feels like a visual representation of pure intellectual thought, with the chalk-like marks suggesting a blackboard filled with the accumulated work of mathematical inquiry. 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.
