MARITIME FLAGS is a font package which was designed after the international flag code. Each flag represents a letter or number. These would be flown on board a vessel, not printed. However, the monochrome font can be used to add a decorative or nautical motif.

The free download font is the single-color font as shown in black above. In practice, the flags use red, blue, black, yellow, and white. On request, I'll send you the full set of four fonts which can be layered to get the full-color effect.
