If you know how many there are, finding most or all of them shouldn't be

middle of Cornhill.

I can think of a fair few which one wouldn't be able to find unless
you knew *exactly* where to look.

A few examples off the top of my head:-
1) Southampton Street
2) one in the middle of a plant depot in Bow
3) one in the middle of a council estate between Stratford and Leyton
4) Elephant & Castle Sidings (in the bowels of the shopping centre)
5) Cambridge Park
6) Bressenden Place
7) Grass Area 14

Et cetera...

And are we sure that the Greathead statue is actually atop a vent
shaft?
