The familiar white flag has a blue anchor and key in saltire with an oak wreath, variously solid blue or blue-outlined. The key represents Bremen, the anchor the sea and the oak leaves traditional German power. Loughran dates adoption probably to 1870. Reed 1901 enlarges and shifts the emblem towards the hoist; Reed 1912 gives black charges. Brown 1958’s swallowtail is considered an error. A known 1897 armorial depiction differs in minor stylistic details from the later FOTW redraw.
