Geometric rectangles in turquoise, lime green, coral, and black stack and interlock across the composition, punctuated by white starburst and atomic-age motifs that dance through the grid. The pattern radiates the optimistic energy of 1950s artwork with its bold color blocking and rhythmic repetition, creating a lively yet ordered visual harmony. 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.
