An elderly gentleman walks towards Hyde Park Corner. He has a sunken mouth suggesting that he possesses no teeth, a protruding chin speckled with white stubble, and wears a thick, knitted woollen hat. In his left hand he carries a boxy, bright red canvas shopping bag. On the side of the bag is printed, in bright white capitals, the word “EROTICA”.
