Concentric rectangles in shades of deep red, bright orange, and golden yellow radiate outward from a dark burgundy center, creating a hypnotic optical effect. The geometric precision and warm color progression evoke the bold graphic sensibility of 1970s modernism, with clean edges and balanced symmetry that draw the eye inward then outward in rhythmic waves. 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.
