A comprehensive chart of maritime signal flags arranged in orderly rows displays the full alphabet and numerical system in bright primary colors, each flag rendered in clean, geometric shapes with bold stripes, solids, and crosses. The composition sits centered on a white ground with a small anchor symbol anchoring the title below, creating an educational yet decorative reference guide with a modern, graphic sensibility. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
