A quick bit of genius to share

Found in an interview with Dave Trott; one of his favourite adverts:

It's so simple, but it actually takes a while for its genius to sink in fully. The "by tube" pun. The fact it ends at Pimlico (the station shown on the tube of paint). The immediate visual schemas for "art" and "London".

And if that isn't enough fun, you could try looking at where the Jubilee line ends and try to work out what year this might have been produced...
