A grid of interlocking triangles in primary and secondary colors creates a dynamic tessellation that recalls mid-century modernist geometry. Bright yellows, reds, and blues alternate with deep browns, blacks, and pinks across a white ground, their sharp angles and bold color blocking evoking the optimistic spirit of 1950s artwork innovation. 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.
