Concentric squares in red radiate outward from the center of a teal ground, their edges aligned with optical precision to create a hypnotic sense of depth and movement. The rhythmic repetition and high-contrast color pairing generate a pulsing visual energy characteristic of Op Art, where the interplay of geometric forms appears to shimmer and advance off the surface. 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.
