Here’s the second of the numerous phone boxes along my pleasant walk from Highbury Fields parkrun to the Thistle City Barbican.

This phone box is a K2 model (I’ve mentioned before that you can distinguish these by the slightly more bulbous top), which is quite a common sight in central London – less so elsewhere.
