Stacked copper circles and geometric lines form an Art Deco grid pattern against a deep emerald background, creating a rhythmic visual meditation on symmetry and balance. The warm metallic tones glow softly against the cool teal field, evoking both the precision of mathematical diagrams and the ornamental luxury of 1920s artwork. 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.
