People
In Islington you can hardly hurl a brick without hitting three antique shops, an estate agent and a bookshop.

Our reading
An editorial interpretation.
A comic map of a neighborhood by shop type. The speaker exaggerates that you can barely throw a brick in Islington without hitting three antique shops, an estate agent and a bookshop. The hurled-brick image makes the crowding sound almost violent.
