The FOTW flag illustration is based on the 1957 German shipping-company chart, but omits the letters shown by the source.
Mitchell depicts only the funnel bands, with a note showing the letters CB in a three-sided box, open on the viewer’s left and with its sides not meeting. The annotations read “yellow” and “mark green”. Mitchell uses light blue, whereas Flaggen & Schornsteine indicates dark blue.
