Three geometric polyhedrons rendered in clean line art stack vertically in descending size, drawn in teal, navy, and golden yellow against a soft beige ground. The minimalist composition captures the crystalline forms with precise linework, creating a sense of balance and mathematical harmony through subtle color differentiation and spatial layering. 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.
