A geometric grid of overlapping squares in teal, green, and cream creates an optical illusion that shifts between flat pattern and dimensional depth. The repeating blocks build a hypnotic rhythm where color saturation and placement play tricks on perception, invoking the visual experiments of mid-century modernism. 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.
