Interlocking geometric shapes in shades of yellow, orange, red, green, teal, and tan create a dense, rhythmic composition inspired by mid-century modernism. Small plus signs and crosses scattered throughout the pattern add a playful, structured energy that suggests both atomic-age optimism and the interconnected artwork language of the 1950s. 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.
