Nested rounded rectangles in green, mustard yellow, and navy blue stack vertically in a symmetrical grid, creating an optical rhythm that suggests both retro technology and organic growth. The palette shifts between warm and cool tones while concentric strokes build geometric depth across the composition. 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.
