A comprehensive chart of maritime signal flags arranged in orderly rows against a deep navy background, each flag rendered in bold geometric blocks of red, yellow, white, black, and blue with crisp white letter labels below. The composition is educational yet visually striking, with the flags' simple shapes and saturated colors creating a rhythmic, almost graphic quality that feels both vintage and timeless. 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.
