A white cross divides the flag into red over blue at the hoist and blue over red at the fly. At the centre, a white shield bears a red rampant, double-tailed lion with yellow tongue and crown. A flag found in a Dutch charity shop carried the label of Bonner Fahnenfabrik. Although initially compared with territorial flags, it was identified in 2012 as Rheintrans through Klaus-Peter Bühne’s banner photograph. The cross bars are narrower than in the earlier FOTW image. The lion prompted comparisons with Limburg and Luxembourg, but its intended meaning was not established.
