Bakker’s illustration, sourced to All about Ships & Shipping (1959), is described as three horizontal white-red-white bands in approximate proportions 2:3:2, with white charges on the red band. Rosanoski explains that the merged flag incorporates the partners’ marks: three red bars represent Mi or Mitsu, meaning three, and the white squashed-X symbol is the kanji O.
