Nested squares in saturated hues stack inward toward a small red center, creating a hypnotic geometric tunnel that recedes into itself. The composition moves through cream, burgundy, gold, pink, teal, green, and pale yellow in concentric layers, rendered in flat color with crisp edges that evoke mid-century modern abstraction and op art sensibilities. 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.
