Monochrome photographs show a pale, probably white funnel with a dark, probably black top. Two narrow darkish bands, probably not black, are well separated, with the upper one close to the top. A later vessel has less space between the bands.

Thompson spaces the funnel bands equally from each other and the top, whereas photographs of Arctic Pioneer and Arctic Warrior support the illustrated version. The National Maritime Museum flag is dated about 1955 and measures 1219.2 × 1828.8 mm.
