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. At home in a nautical-themed office, study, or seaside cottage. Printed on glossy aluminum and made to order, ready to hang with the hardware built into the back. Original artwork in a finish that holds its color and resists fading, not a quick print off a shelf.
