Geometric shapes in black and turquoise fill this mid-century composition, where boomerangs, starbursts, and diamond forms create a rhythmic pattern across a bright aqua ground. The interlocking motifs repeat with mathematical precision, evoking the optimistic graphic language of 1950s artwork culture. 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.
