Geometric polyhedra and star forms rendered in precise line work scatter across an aged cream ground, recreating the mathematical diagrams from Kepler's seminal treatise on celestial harmony. The composition balances intricate cross-hatching and linear detail with negative space, evoking the appearance of an antique scientific manuscript through its warm, paper-like tonality and careful Renaissance-era draftsmanship. 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.
