It’s a part of his ‘Hidden Cities’ collection, and was taken during an exploration of Manchester.
I have a lot of his worked saved and hidden away, because it has often served to inspire and save me from more than one bought of writer’s block.
The reason I love this particular picture so much is because I found it when trying to research locations for Underground, back when it was still a short that took place almost entirely inside a series of abandoned tunnels.
Whenever I’m having trouble writing that story, taking a look at Brooks’ work often helps me get back on track.
