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 to order on smooth 100lb gloss paper, then rolled into a tube and shipped ready to pin, tape, or frame. Sized to fill a wall without filling the budget. The same independent-artist artwork you'd frame, at poster scale and poster price.
