This 744 was delivered to Lufthansa in April 1991 and is pictured taxying on to stand. The plane was named 'Düsseldorf' for its commercial life but doesn't appear to carry this name at the time of the picture. The plane was withdrawn from the fleet in July 2015, ferried to Tulsa (TUL), OK and subsequently parted-out and scrapped .

Promoting the German football (soccer) team of FC Bayern Munich. If I had been in the Lufthansa promotions department I would have swapped the aircraft name with that of A380 D-AIMB so that this aircraft carried the name München instead of Mainz (which is not even in Bayern)! Rather a significant oversight to my mind.
