Proletarier aller Länder vereinigt Euch!

I have found appropriate on today's date to take photo of former HQ of ASLEF, the Train Drivers Union. That building (or more accurately what it have represented ) was sort of anomaly for bourgeois Hampstead (despite having Glenda Jackson as local MP).
Building was sold couple years ago to prevent ASLEF's bankruptcy but new buyer (probably some developer) haven't started work on it and building is slowly falling into despair.
