These bright, bold and graphic flags are as eye-catching as they are functional. Based on the International Code of Signals, drafted by the British Board of Trade in 1855, each flag represents a letter in the alphabet and is traditionally used to communicate urgent seafaring messages. Hang these high on your ship's mast or on the walls of home, display just one or the entire set, spell out a coded message, or conjure up the evocative regimen of naval life. Our nautical flags are a fully sewn construction with double-stitched seams, they are resistant to sun and salt and are made in the USA by Annin & Co., the country's oldest and most esteemed flag maker. This full set of flags (26 letters, 10 numbers, 3 substitutes, and 1 answering pennant) comes stowed in an original Best Made navy blue waxed canvas ditty bag (only available with the purchase of flags).
