In 1997 British Airways (BA) adopted a new livery. One part of this was a newly stylised version of the British Airways "Speedbird" logo, the "Speedmarque", but the major change was the introduction of tail-fin art. Also known as the Utopia, World Tails and world image tailfins, they used art and designs from international artists and other sources to represent countries on BA's route network. The signature of the artist was carried near the design on the tail.
