...sadly vandals and the otherwise bored and useless of London decided
to spend Christmas Day at Mile End station. Graffiti artist(s) evidently
had plenty of time to put meaningless scrawls on most surfaces and
hoardings on the platforms. I didn't bother venturing off the very
crowded train to see if they had defaced the booking hall.

Earl's Court District Line platforms have also been hit.

Any others?

Arsenal, Holloway Road and Caledonian Road on the Piccadilly line. Now
how did they get in there?
