A grid of vertical book spines in warm oranges, deep browns, soft blues, and hot pinks creates an orderly yet playful composition that evokes a mid-century bookshelf. The stacked rectangular forms, punctuated by white dividing lines, establish a rhythmic pattern that balances geometric precision with the organic variety of color blocking. 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.
