Interlocking geometric shapes in shades of blue, teal, and white form a rhythmic composition that recalls the modular logic of mid-century artwork. Rounded corners, nested rectangles, and scattered circles create a sense of ordered play, as if abstract building blocks have been arranged with both precision and whimsy. 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.
