A special guest plaque this week, sent to us by one-time Londoner Fred. (Fred blogs about life in Kinshasa, in the "Democratic" Republic of Congo. Extra Extra is a bit like a Congolese version of Londonist - only with much harder cops.)
But back to London...where can this plaque be found? (The easy part.) And who was Julian Wall, other than a 'totter, squatter a true individual'?
