Concentric rectangular rings arranged in a tight geometric grid create a hypnotic, optical effect across a black ground with crisp white outlines. The pattern suggests mid-century atomic imagery with its ordered, repeating structure and stark monochromatic palette, evoking the precision and optimism of 1950s artwork sensibility. 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.
