3Though they seem as immutable and traditional as the city they serve, London's bus routes are always changing.

In this snapshot of 2021, Matthew Wharmby captures routes 1-100 at their current physical extent and with their current operating company. Illustrated with over 180 up-to-date photographs, this unique volume gives an insight into what can be seen on each route every day.
