Concentric black rings radiate outward from a center point, echoing the geometric optimism of mid-century atomic artwork. A bold mustard yellow L-shape frames the left and bottom edges, creating a dynamic composition that balances the organic curves of the rings against clean, angular geometry. 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.
