The map above shows the first image returned in a Google image search for all 32 London boroughs (excluding maps, which were commonly the first result).
It's a lively mix. Only a few boroughs, such as Islington, Greenwich and Southwark, show local landmarks. Some are surprising, such as the humdrum Edwardian lamp post fielded by Ealing. Other boroughs are amusingly represented by unconnected namesakes - Redbridge beer, Corporal Thaddeus S. Sutton, the Enfield motorbike and 'gay pornographic actor' Brent Corrigan.
