A dense grid of hand-drawn maritime signal flags fills the composition, each small square containing a flag artwork rendered in red, blue, green, gold, and cream with intricate patterns and symbols. The overall effect is encyclopedic and methodical, presenting a comprehensive visual catalog of international naval communication in warm, antiquated tones that suggest a 19th-century maritime reference book. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
