I have to say that this is a slightly baffling piece by Gustavo Nenao in Leake Street tunnel. It is a photorealistic portrait of Nelson Mandela wearing a not very photorealistic party hat with Happy Birthday written on it. While the subject matter is certainly curious, the execution is perfect, especially as the portrait is in black and whiite, with so many shades in it.
I am guessing it was done as a birthday tribute to the great man himself, but can’t be sure, and hey – I was in London which is way outside my normal stamping ground and I feel no pressure to know anything about anything on the street scene there. I come as a tourist, just like everyone else. A querky and excellent piece.
