Seven horizontal rectangular bars in varying shades of blue, from pale slate to deep navy, are stacked with subtle white gaps between each one against a warm cream background. The composition is spare and geometric, rendered with clean edges and a restrained mid-century modern sensibility that emphasizes color gradation and minimalist form. 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.
