This is an example of a Boeing 747-400 (customer code: 51) in service with Northwest Airlines after the early 2000s when the Blowing Shoe Paint Scheme was replaced by the Compass Livery. The livery was hand-picked from a number of choices. It was removed after Delta Airlines and Northwest Airlines merged their operating certificates in 2009.
