Three stacked atomic structures radiate outward in symmetry, their spoked centers connected by horizontal lines that suggest scientific precision and order. Circles in sage green, deep navy, soft gray, and bright yellow cluster around each hub, evoking the optimistic geometry of 1950s atomic imagery with a calm, measured palette. 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.
