Airport is also open so was either first seen in 1991 or was branded before hand but remained around for the Airport extension opening.
That Braathens livery was about for quite a while - no idea on dates though.
Definately one of the first advertisement liveries, if not the first.
Saying that, struggling to think of the ones which followed in the following few years after.
There may have been a Metroland livery - but not sure on others.
