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. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
